The density of a solution containing 13% by mass of sulphuric acid is 1.09 g/mL. Calculate the molarity of the solution :–

(a) 1.445 M

(b) 14.45 M

(c) 144.5 M

(d) 0.1445 M

Correct Option (a) 1.445 M

Explanation

Volume of 100 gram of the solution = 100/dMolarity = No.of ***** of H2SO4/Volume of solution in litre= 13/98 x 1.09 x 10/1 = 1.445M
