How to measure volume of a gas?
Normally, u should use a gas syringe.
However, the point is when opening a can its difficult to direct the gas to the syringe. Remember its an O-Level question and the examiner is surely not looking for an extravagant process.
A simple answer like telling the person to open the can in a plastic, one end being fixed to the gas syringe should allow you to get full marks. You can draw a diagram to make your answer clearly.
