Question

An aqueous solution contains 38 hcl by mass calculate the molality of the solution

Answer 1

Molarity    M   = (X)   x d  x 10  /  m B.

                     38  X   1.19   X 10  / 36.5

                     12.38M.

Like wise , molarity  = No of moles of HCl  / mass of water in kg.

                           = 12.38  /  mass of water in kg.

Answer 2

12.38 is answer
Ok
