Assuming ideal behavior, what is the density of argon gas at STP, in g/L?
A)0.0176 g/L
B)0.0250 g/L
C)0.0561 g/L
D)1.78 g/L
E)181. g/L

Quizplus · Accepted Answer

At STP (standard temperature and pressure), 1 mole of an ideal gas occupies 22.4 L. The molar mass of argon is approximately 39.95 g/mol. Therefore, the density is 39.95 g/mol divided by 22.4 L/mol, which equals approximately 1.78 g/L.
