1 mol of Xe gas at 345 K will have a greater distribution of molecular speeds and higher average speed than 1 mol of Ne at the same temperature.

A 0.23 dm³ sealed container is filled with 3 mol of He, with a root mean square molecular speed, c = 1250 m s^-1. Find the pressure exerted by the gas (in k Pa).

Calculate the root mean square speed of hydrogen chloride gas at 17 °C. Give your answer in m s^-1.

A gas-mixing cylinder is filled with a mixture of He, Ne and Ar, in a 1:1:2 ratio. The total pressure in the gas-mixing cylinder is 3.10 × 10⁵ Pa. Calculate the partial pressure of helium in the mixture.

A 22.0 L gas cylinder at 5.2 atm and 23 °C contains only carbon monoxide gas. What is the mass (in kg) of carbon monoxide in the tank?

As the temperature increases of a fixed amount of gas, at a constant pressure, its volume decreases.
