An 8-litre cylinder contains a mixture of oxygen and nitrogen, the volume of oxygen being 16% of total volume. A few litres of the mixture is released and equal amount of Nitrogen is added, then the same amount of the mixture as before is released and replaced by nitrogen for the second time.As a result the oxygen content becomes 9% of the total value.
