Introduction:
The purpose of this experiment was to determine the molar mass and the identity of an unknown volatile liquid. Being volatile means that it has a high vapor pressure, and can thus be easily transformed into gas. This type of liquid usually operates like an ideal gas when transformed into vapor. Thus, we can apply the ideal gas law to calculate the moles of the unknown liquid:
PV=nRT
P is the pressure of the vapor in atmospheres, V is the volume of the vapor in liters, n is the amount of the vapor in moles, T is the temperature of the vapor in Kelvin, and R is the ideal gas constant. The value of the ideal gas constant changes depending on what unit of pressure and volume is used. In this case, since atmospheres and liters is used,

Alka-Seltzer Co: Two Gases

The ideal gas law, PV=nRT, was a formula that determined the number of moles produced. Taking the Barometric pressure, 769.9mmHg, and subtracting it from the volume of water, 17.5 mmHg, can formulate the pressure. Since pressure is what’s needed, 752.4 had to be divided by 760 to be converted into atm creating 0.99atm. Then with plugging in the rest, using .0821 and (20+273), the number of moles can be found by getting n, moles, alone. The answer then is .0298 moles of gas produced.…

Following, the samples were then transferred to the furnace for total oxidation of carbon, hydrogen, and nitrogen. The second run through the furnace removed unwanted particulate materials. The gases from the combustion were collected into a cooler to remove water vapor; then contained in a ballast for equilibrium. At this point in time, the gases in question were separated by their respective carrier gases and concentrations could be accounted…

Imagine trying to figure out one possible combination to a mixture, when there are over 100 possibilities. The 8th graders had to look at the physical and chemical properties, to somehow figure out the mixture. A group of students thinks that Baking Soda and Citric Acid is what’s in the mystery mixture. That group thinks that Baking Soda and Citric Acid is in it for a lot of reasons. One reason is that the mystery mixture has circular round objects in it and the Citric Acid is circular and round.…

Reaction Between The Calcium Chloride And Phhenol Red

The lab had calcium chloride and sodium bicarbonate placed with the same bag and then red phenol was added and the chemical substances were mixed together. The result was a rapid increase in the gas within the bag, one substance turned a bright yellow and the other a fuchsia pink. The yellow substance was very warm while the pink substance was cold. From this lab three experiments were created in one mixed calcium chloride with red phenol to see if the calcium or the sodium bicarbonate was the reason for the gas in the bag. There was no gas expansion so it can be inferred that the sodium bicarbonate was the cause for the gas.…

Yes, the amount of water in the lighter could be a huge factor for the molar mass of the butane to be more than the actual molar mass. The experimental molar mass would probably be more accurate if the lighter was weighed without being wet and after releasing the butane the lighter was set out for a while for the water to evaporate and it was weighed…

By tapping into the unknown world of gases, Priestly challenged and dethroned the idea that “air is a simple elementary substance, indestructible and unalterable”, a concept that had “dominated science for 23 uninterrupted centuries” (Joseph Priestley and the Discovery of Oxygen). Priestley discovered 10 new gases: nitri Priestley discovered 10 new gases: nitric oxide (nitrous air), nitrogen dioxide (red nitrous vapour), nitrous oxide (inflammable nitrous air, later called “laughing gas”), hydrogen chloride (marine acid air), ammonia (alkaline air), sulfur dioxide (vitriolic acid air), silicon tetrafluoride (fluor acid air), nitrogen (phlogisticated air), oxygen (dephlogisticated air, independently codiscovered by Carl Wilhelm Scheele), and a gas later identified as carbon…

Analysis Of Acetone And Toluene

After starting with 30 mL of an unknown mixture of two solvents, fractional distillation and gas chromatography were used to identify the unknowns as acetone and toluene in a 1 to 2.04 ratio of acetone to toluene. Fractional distillation was first used to separate the unknown mixture into its components based on boiling point. Distillation refers to the method of separating components of a mixture through heating and cooling. Simple distillation, which is especially useful in the separation of less-volatile substances from volatile substances, such as sugar from water, can be used to separate a liquid-liquid mixture if the boiling points of the component liquids differ by more than 40-50°C. A plot of temperature versus volume for a simple…

Introduction Density measures the volume that a given amount of mass takes up. Usually, density has grams per unit volume as a unit. To find the density of an object, the object has to be measured and its mass has to be divided by its volume. Often times, density is used to identify substances, since different elements have specific densities. This experiment is made up of two sections; the first section measures the density of water and the density of an unknown substance.…

The Ideal Gas Law, Boyle's Law

This is due to the volume in mL being multiplied by the pressure in kPa. Using the equation, PV = k, and the average constant, k, 1052.85 mL*kPa and the 2.5 mL volume, the pressure can be solved. The resulting pressure value is 421.14 kPa. When the volume is 40 mL, the pressure value is 26.32 kPa when the constant is the same value. The volume of 40 mL is 16 times as much as the volume of 2.5 mL. The pressure of the 40 mL was 1/16th of the pressure of the 2.5 mL. The pressure values of 2.5 and 40 mL were also 16 times greater than the other.…

Molar Volume Of Gas Lab Report

Molar volume is the volume occupied by one mole of a gas, in this case, hydrogen gas. Molar volume relates to the lab as the entire purpose of this lab is to find the molar volume of hydrogen gas at STP. The ideal gas law describes a relationship between pressure (P), volume (V), the number of moles (n), temperature (T), and the universal gas constant (R) where PV = nRT. This ideal gas law is essential to the lab as it explains the relationships between the different measurements of a gas and reduces into the combined gas law. The combined gas law is a relation where the number of moles of gas is constant, thus leaving the variables of pressure, volume, and temperature.…
