If at a particular tempreture, the density of 18M H_(2)SO_(4) is 1.8g Cm^(-3), calcualte: (a) Molality, (b) % concentration by weight of solution (c ) Mole fraction of water and H_(2)SO_(4), (d) Relative decrease in vapour pressure with repsect to H_(2)O solvent assuming H_(2)SO_(4) almost unionised at this high concentration.

Answer»


Answer :(a) `500` molal, (B) `98%`,(C ) `H_(2)SO_(4) = 0.9, H_(2)O = 0.1`,(d) `0.9`;
