What is the density of oxygen gas at STP?
A) 0.700 g/L
B) 0.0450 g/L
C) 2.90 g/L
D) 1.43 g/L

Quizplus · Accepted Answer

At standard temperature and pressure (STP), the density of oxygen gas (O2) is 1.43 g/L. This can be calculated using the formula: density = (mass of substance) / (volume of substance). The molar mass of oxygen is 32 g/mol, so one mole of oxygen gas (O2) at STP occupies a volume of 22.4 L (as per Avogadro's Law). Therefore, the mass of one mole of oxygen gas at STP is 32 g, and the density of oxygen gas at STP is (32 g) / (22.4 L) = 1.43 g/L.
