Higher is the _____ (mass/volume) of solute in a solution lower is its vapour pressure.



A non volatile solute ________ (decrease/increase) the rate of evaporation of the solvent and thereby lowers the vapour pressure of solvent.



The vapour pressure of ethanol and methanol are 44.5 mm and 88.7 mm Hg respectively. An ideal solution is prepared at the same temperature by mixing 60 g of ethanol with 40 g of methanol. Calculate total vapour pressure of the solution.



Sugar and Salt solutions are________.



103 mol of CuSO45H2O is introduced in a 1.9 L vessel maintained at a constant temperature of 27C containing moist air at relative humidity of 12.5%. What is the final molar composition of solid mixture?
For CuSO4.5H2O(s)CuSO4(s)+5H2O(g),Kp(atm)=1010. Take vapor pressure of water at 27C as 28 torrs.
