Quizplus · Accepted Answer

At STP (Standard Temperature and Pressure), 1 mole of any gas occupies 22.4 liters. The molecular formula for nitrogen gas is N2, and the atomic mass of nitrogen (N) is approximately 14 g/mol. Therefore, the molar mass of N2 is 28 g/mol. Thus, 22.4 liters of nitrogen gas at STP will have a mass of 28.0 g.
