Question

The concentration of the solution containing 35 g of sodium chloride dissolved in 100 g
of water at 293 K is
(A) 27.92 %
(B) 2.59 %
(C) 25.92 %
(D) 2.79 %

Answer 1

Answer:

x100

Explanation:

Mass of solute = 36 g

    Mass of solvent = 100g

    Mass of solution = 100 + 36

                           = 136g

Concentration of solution = (Mass of solute / Mass of solution ) x100

                                  = (36/136) x 100
