Which can be a unit of vapour pressure?

Answer and explanation

Correct answer: Pascal

Vapour pressure is a pressure, because it is the force per unit area exerted by vapour particles. The SI unit of pressure is the pascal (Pa); other pressure units include atmosphere, bar and millimetre of mercury. Gram measures mass, litre measures volume, and mole measures amount of substance, so they cannot be pressure units.
