Assuming ideal behavior, what is the density of argon gas at STP? (R = 0.08206 L • atm/K • mol)
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 calculated as 39.95 g/mol divided by 22.4 L/mol, which equals approximately 1.78 g/L.
