At a standard temperature, a pressure that is 0° C and 1.01 x 105 Pa pressure, thedensity of oxygen is 1.43 kg m-3.Oxygen is stored in a container of volume 3.87 m3at a pressure of 2.02 x 105 Pa at atemperature of 25°C.i. What volume would the same mass of oxygen occupy at a ‘standardtemperature and pressure’? calculate the mass of oxygen in the container.
