Gce Model Questions Vol1 2019 Chemistry Question 7
Practice objective / multiple choice question 7 from the 2019 Gce Model Questions Vol1 Chemistry examination.
A 2.0 L sealed container at 25 °C holds a mixture of water vapour and nitrogen gas. The total pressure is 1.20 atm and the vapour pressure of water at 25 °C is 0.0313 atm. (a) Determine the partial pressure of nitrogen and the amount (in moles) of nitrogen present. (b) The temperature is then raised to 50 °C while the volume remains unchanged. The vapour pressure of water at 50 °C is 0.123 atm. Assuming nitrogen behaves ideally and the water vapour stays at its saturation pressure, calculate the new total pressure in the container.
