Document Summary

To calculate the molar volume of co2 gas (in l/mol) by determining the mass of a known volume of co2 gas at laboratory temperature and pressure. The molar volume we calculate is at stp (as de ned in 1. 1): = p2v2 n2rt2 where the left equation represents laboratory conditions, and the right equation represents conditions at. Stp the standard temperature is 273 k (0 c) and the standard pressure is 1 atm. Ideal gas minimal interactions of gas molecules, which happens at high temperature and low pressure. The molar volume of an ideal gas at stp is 22. 4 l. 2 experiment: weigh an empty ask with a stopper, obtain a piece of dry ice (co2(s)) and place in the ask, let the solid co2 vaporize. Measure up to full-capacity in the graduated cylinder, empty it, then measure the remaining h2o.
