An aqueous solution of methanol in water has vapour pressure

Question

An aqueous solution of methanol in water has vapour pressure (A) equal to that of water (B) equal to that of methanol (C) more than that of water (D) less than that of water

Tardigrade Admin · Accepted Answer

An aqueous solution vapour pressure is more than that of water but less than that of methanol. This is because the vapour pressure of pure methanol at the same temperature is more than that of water.
