CHEMISTRY 2001 NAME PROBLEM SET #10: Gas Law Problems II DATE PERIOD Background: o C and 760 mmHg. At STP, 1.00 moles of any gas occupies 22.4 Liters. When used in a problem, the proper unit label would be 22.4 L/mol. At 25 o C (room temp) and 760 mmHg, use 24.4 liters/mole. 1. Why is it necessary to compare volumes of gas only at the same temperature and pressure? 2. Calculate the volume, in liters, of 3.00 moles of nitrogen gas.
