The objective of this lab experiment is to measure the material in the gas phase and to see how the ideal gas experiment could apply to the physical. In this the material we used was, a sip-lock plastic bag, a large plastic beaker, thermometry, dry ice, water, and butane lighter.
In this lab, the experiment focused on the relationship between the temperature and pressure of an ideal gas that was dry ice inside the closed container. Therefore, the volume remains constant because the ideal gas was in a closed container.
Experiment Procedure
First, all the materials were collected. After collecting all the materials was prepared, we started measuring the mass of the beaker and plastic

This due to continues loss of carbon dioxide that makes the bag to inflate slowly each time all the carbon dioxide is released. After adding 5 ml of H2O to the dry ice the plastic was seen to inflate a little faster than it was and dry ice changed in to wet dry ice. However, if we had less than 25 g of dry ice then the inflated process could be slower. After getting the barometric pressure, the value of the gas contain “R” was calculated for the trials by using the equation. R=PV/NT. After that the mean value of the gas constant and percent error for all trails was calculated. Result and Discussion After finishing the experiment and doing the calculation that required for this experiment. After having all the data required, number of butane gas molecule was calculated for each trial. The MW was calculated by dividing the mass of butane by number of mole of butane. After that the average MW were calculated.
The rate at which the plastic bag inflated depended on the mass of the dry ice present inside the bag. So, it can be conclude that the rate at which the bag inflated on the mass of the dry ice associated. Overall, the experiment succeeded in showing that temperature and pressure for an ideal gas at constant volume and mass follow the relation of ideal gas equation.

Results: 1. Determination of the Ideal Gas Constant R using CO2
Mass of Beaker and Bag (g): 61.615g Approx.
