1.	Ques 1: Calculate the molarity of a sulphuric acid solution in which the mole fraction of water is 0.85.
Answer» ong>EXPLANATION: MOL FRACTION of water in SOLUTION = 0.85 So mol of acid = 1-0.85 = 0.15 Now m= nw×molecularwtofwater 1000×molofacid m= 0.85×18 1000×0.15 =9.8mol/kg

Ques 1: Calculate the molarity of a sulphuric acid solution in which the mole fraction of water is 0.85.

Answer»

MOL FRACTION of water in SOLUTION = 0.85

So mol of acid = 1-0.85 = 0.15

Now

m= nw×molecularwtofwater

1000×molofacid

m= 0.85×18

1000×0.15

=9.8mol/kg
