A 75.0 g sample of dinitrogen monoxide (N2O) is confined in a 4.12 L vessel. What is the pressure (in atm) at 205.0°F, given that the ideal gas constant R is 0.0821 L·atm/mol·K?

Nitrogen dioxide (46.0 g/mol) forms from nitric oxide (28.0 g/mol) and oxygen (32.0 g/mol):2 NO(g) + O2(g) → 2 NO2(g)What is the volume change of the system when 36.0 g of NO2 is formed at a pressure of 1 atm and 300 K, assuming ideal gas behavior?

What is the density of ammonia gas (NH3) at a pressure of 2.00 atm and a temperature of 25.0°C, assuming ideal gas behavior?

A cylinder contains 1.00 mol of an ideal gas at constant temperature and pressure. What will its volume be if an additional 0.340 mol of gas is added to the cylinder?

What is the pressure in mm of Hg of a gas mixture that contains 1g of H2 and 8.0g of Ar in a 3.0 L container at 27°C?

What is the pressure exerted by a 75.0 g sample of N2O confined to a 4.12 L vessel at 298 K, assuming ideal gas behavior? (Molar mass of N2O = 44.01 g/mol, R = 0.0821 L·atm/mol·K)
