Document Summary
Curt kim, jonathan lee, keshav mantha, bobbie sheng. Goal: the goal of this lab was to measure the masses of equal volumes of two different gases and calculate the ratio between the molar mass of the gases. Procedure: first, a 560 ml erlenmeyer flask filled with air was massed along with its connected clamp and rubber tube. The flask was then filled with methane through the rubber tube, and the flask assembly was massed again with the tube sealed shut. After the new mass was recorded, the flask was emptied and another trial of methane gas was conducted. Next, the same process was repeated for another two trials with carbon dioxide gas instead of methane. Finally, the current room temperature and pressure readings were noted. Analysis: calculate the mass of the air in the empty flask. In all four trials for the two gases, the volume of the flasks were 560ml.
