A vessel which contains 300 dm3 of nitrogen gas at 25 °C and 100.3 kPa is contaminated with carbon dioxide and water vapour. The mixture of gases is passed through concentrated sulphuric acid to remove the water vapour and a mass loss of 1.00 g is observed. Then, the mixture is bubbled through concentrated sodium hydroxide solution, a further mass loss of 16.20 g is observed. Calculate the partial pressure of each component in the mixture.
