By examining Figure 4, we can see the relationship between density and molar mass to be a proportional relationship. The positive slope of the scatter plot confirms this relationship. This means that as molar mass of is greater, the density of the gas will also be greater, and if the molar mass of a gas is smaller, the density of the gas will be smaller. For example, hydrogen gas will have a lower density than nitrogen gas because hydrogen has a smaller molar mass than nitrogen.…

The Relationship between Mineral Type and Density (g/ml) Purpose/Introduction: The purpose of this lab was to understand the relationship between minerals and density, the ratio of mass to volume, particularly, how density can be used to identify mineral type. In the lab, two samples of the mineral, feldspar, were measured for mass and volume in order to calculate their density. Many of the mineral tests yielded qualitative data, such as color, streak, luster, and crystal shape, which can be…

Experiment 2: Aim: In this experiment you will determine the mass of a single drop of water by a graphical method. You will evaluate its uncertainty. Data: Table 1: Number of Drops: Mass of Beaker + drops/g (0.01g) 1 2.36 g 2 2.38 g 3 2.40 g 4 2.44 g 5 2.46 g 6 2.48 g 7 2.50 g Chart 1: Analysis: The mass of 1 drop of water is 0.4g. By taking the total mass and dividing it by the number of drops we can figure out the average mass of a drop of water. However the number of drops should…

An introduction to the Balance and the Determination of Density Purpose: To make measurements and collect data to determine the physical properties of matter; density, volume, and mass. Materials: Graduated Cylinder Balance Water Unknown Liquid Paper Towels Weighing Paper Weighed Solid (Rubber stopper) Procedure: Part A Obtain a 10 ml graduated cylinder and measure its mass on the balance. Record. Pour water inside the graduated cylinder. In other to get the correct measurement of volume, read…

the volume lab, we found that the large graduated cylinder was the most accurate because it had less percent error when measuring the density of water over all of the other measuring tools.In this lab, we measured water from pipettes including volumetric and graduated pipettes, graduated cylinders, erlenmeyer flasks, and beakers to figure out the mass and density. These measurements were then used to calculate the percent error. We completed these measurements by measuring the volume of the…

initial mass of the beaker was subtracted to obtain the grams of water in the beaker. Using the temperature of the water, the density could be found, allowing for the theoretical volume of the water to be found. The percent error could be found once we had the theoretical volume compared to the measured volume. The water trails were similar in temperature, thus the density were similar throughout the experiment. The burette trails had an average percent error of -0.466% compared to the…

Density Open Response Density Density is the mass per unit of volume of a substance. Density is measured in grams per milliliter (g/mL), or grams per centimeters cubed (g/cm3). The density of an object is what causes it to sink or float. If an object has higher density than the liquid it is being placed into, it will sink. If an object has a lesser density than the liquid it is being placed into it will float. For example, the density of…

ratio of M-S-H binder In development of M-S-H binder with magnesium oxide and silica fume, it is noted that silica fume has rather low specific gravity (S.G) and bulk density compared to Portland cement (PC). Thus, use of high silica fume content in the binder consequently results in a binder system of low specific gravity and bulk density, compared to PC. The light weight binder leads to a difference in water to binder ratio (by mass), compared to PC. To compare water content by mass of M-S-H…

When the egg was placed into syrup, a hypertonic solution, it shrunk in size. This result supports my hypothesis. The mass of the egg before it was placed in syrup and after it was placed in syrup changed drastically. There was a 16 g decrease in mass that happened to the egg during its time in the syrup. Both the long and short circumference of the egg decreased. The long circumference before the egg was placed in syrup was 18.75 cm and after it was taken out of the syrup the long circumference…

of the eggs is greater than the density of water. Then salt water 1-2 a spoon and stir in the eggs slowly, still also sank because of the eggs is still greater than the density of water. Drift An object that is dipped into the liquid will float if heavy objects are similar in style to the top or the object in equilibrium By the time the water was given a 2 ½ spoon of salt and stir gradually then egg will be on a State of drift. This happens because the density of water is equal to the mass…
