The density of O₂ gas at STP is

Question

Quizplus · Accepted Answer

At standard temperature and pressure (STP), the density of any gas is 1.43 g/L. This is because STP is defined as a temperature of 0°C (273.15 K) and a pressure of 1 atmosphere (1 atm), and the molar volume of any gas at STP is 22.4 L/mol. Therefore, to find the density of a gas at STP, we simply divide the molar mass of the gas by the molar volume at STP: (32 g/mol) / (22.4 L/mol) = 1.43 g/L. Since the molar mass of O₂ is 32 g/mol, the density of O₂ gas at STP is 1.43 g/L.
