Solution: What is the volume occupied by 18.6 g of argon gas at a pressure of 1.19 atm and a temperature of 394 K? Express your answer with the appropriate units. Compare the volume of 18.6 g of helium to 18.6 g of argon gas (under identical conditions). The volume would be greater for helium gas. The volume would be the same for helium gas. The volume would be lower for helium gas.
