Question

Part A) The density of a sample of N2O gas is 3.00 g/L at 298 K.What is the pressure of the gas (in mmHg)?

Part B) An experiment shows that a 110 mL gas sample has a mass of 0.173 g at a pressure of 751 mmHg and a temperature of 30 ∘C.

What is the molar mass of the gas?

Part C) A gas has a density of 2.07 g/L at a temperature of 24 ∘C and a pressure of 0.787 atm . Calculate the molar mass of the gas.

Express the molar mass to three significant figures and include the appropriate units.

Part D) Calculate the density of argon gas at a pressure of 749 mmHg and a temperature of 50 ∘C.

Express the density to three significant figures and include the appropriate units.
