What is the weight % sulphuric acid in an aqueous solution which is 0.502 M in sulphuric acid? The specify gravity of the solution is 1.07

A.4.6 %✓ Correct

B.5.67 %

C.9.53 %

D.22.0 %

Explanation

Molarity ( ) Moles of solute Volumeof solution L Molarity = 0.502 (given) i.e. 0.502 moles of solute in 1L solution i.e. 1000ml of solution. ∴Weight of 2 4 H SO in0.502 98 49.2 x g 1000ml of solution Weight of solution 1.07 1000 1,070 V x x g ∴%Weight 49.2 100 100 4.6% 1,070 Weight of solute Weight of solution x x The correct option is (a)
