Formal Lab Report: Molar Volume of a Gas at STP Abstract: The purpose of this experiment is to find out how to experimentally determine what the volume of a mole of H₂(g) is at STP by using gas laws. The hypothesis for the experiment is that if H₂(g) is produced at RT and STP, Avogadro’s law can be used to experimentally determine the amount of H₂(g) because equal gases at the same pressure and temperature have the same amount of particles. In order to find the molar volume, hydrogen gas…

Results A total of 383 scallops were collected in this survey, with scallops present on 66 out of the 151 transects surveyed. The mean size (ANOVA, F(380, 2)=13.9, p< 0.05) and recreational area (p<0.05) (Table 2). The greatest average density per site was observed within Paterson Inlet with 0.21 scallops per m2 at site M2, in the inner inlet (Figure 2). The next highest average density per site was found at site M9 in the outer inlet with a density less than half of the greatest density…

The amount of flour added to a cookie recipe does affect the height of a cookie. The question for this experiment is “Does changing amount of flour affect the height of the baked cookie”? The hypothesis of this experiment is if less flour is added to a cookie recipe,then the cookie will rise in height. The amount of flour is the independent variable and the height of the cookie is the dependent variable. The control variables are the oven temperature, the cookie recipe, and the ingredients…

would emphasize our ultimate goal in our planning stage. The main goal for Fulfillment Operations was to meet our one-day service level agreement and utilize capacity effectively. We would do this by assigning volumes appropriately…

Aim The aim of this practical is to measure the effect of volume, density and temperature. It is also help to be familiar with variety of common laboratory technique. Materials Weighting scale Container with lids 20 and 10 ml Volumetric pipette Beaker Thermometer Test Tubes Volumetric flask Natural Rubber Pipette Filler Micropipette tips Tips boxes Method There are two pipette, choose one which you using in whole practical. Label and weight accurately, to 4 decimal places. Collect…

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 subjective. Other…

uncertainty being only 0.4%. The pipette could be replaced with a volumetric pipette. This would allow for us to be able to measure the amount of water that is placed within. Therefore a drop would be more accurate as we could control the amount of volume that is lost from the pipette. Maybe it would've been better to use a different balance beam of the same model to determine whether the original balance beam is faulty or if that brand is not very…

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 bottom meniscus. Determine and record the mass of the graduated cylinder and…

In 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…

One of the most important activities of science is measurement. Measurement is a means of quantifying properties for identification. For example, density is the relationship between the mass and volume of a pure substance. One could determine if a piece of yellow metal is gold by determining its density. Measurement allows scientists to make comparisons. Measurement also provides a means by which scientists can judge the reproducibility of an experimental procedure. However, measurement is not…
