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 44.5mm and 88.7mmHg respectively. An ideal solution is prepared at the same temperature by mixing 60g of ethanol with 40g of methanol. Calculate total vapour pressure of the solution.
Sugar and Salt solutions are________.
10−3 mol of CuSO4⋅5H2O is introduced in a 1.9L vessel maintained at a constant temperature of 27∘C 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)=10−10. Take vapor pressure of water at 27∘C as 28 torrs.
