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?
