Molar Volume and Molecular Weight of Gas Group Participants: Jason Christian, Connor Dennis, Josh Istas Section Number: 416 Meeting Time: 7:30-10:20 August 31, 2006 TA: Amanda Reeves Introduction The Molar Volume of a gas is the volume per mole. The molar volume of an ideal gas at STP is 22.414 L/mol. STP is 273.15° K and 1 atm of pressure. By using the ideal gas equation, PV = nRT, the molar volume can be determined. Also, the density equation ρ = m/v is needed. The Molecular Weight of Air is determined by using the ideal gas equation. Experimental Experiment A Find the mass of a balloon and rubber stopper using a top loading balance. Add dry ice (CO 2 (s) ) to the balloon and quickly place the stopper on the balloon. Find the mass of the balloon, stopper, and dry ice. Shake the balloon until all surfaces are room temperature. Measure the mass of the balloon, stopper, and CO 2 (g) after sublimation occurs.
