Molarity of Nacl solution

When 5.85 g of NaCl (having molecular weight 58.5) is dissolved in water and the solution is prepared to 0.5 litres, the molarity of the solution is: (i) 0.2 (ii) 0.4 (iii) 1.0 (iv) 0.1

E

Expert

Verified

The right answer is (a)

M = W/Molecular Wt x volume in litre = 5.85/ 58.5 x 0.5 = 0.2 M
