Container A holds 737 mL of ideal gas at 2.30 atm. Container B holds 119 mL of ideal gas at 4.60 atm. If the gases are allowed to mix together, what is the resulting pressure?

4.05 g of an unknown gas at 35 °C and 1.00 atm is stored in a 1.35-L flask.
what is the density and molar mass of the gas?

Dry air (0% humidity) is approximately 78% N2, 21% O2, and 1% Ar by moles. Calculate the molar mass and density of dry air at 0 °C and 1.0 atm. Assume ideal behavior and use two significant figures in your answers.
