Question

Arun has prepared 0.01% ( by mass ) solution of sodium chloride in water, calculate the composition of soltution.

How do you do it ?

Answer 1

We are given that, Mass % of solute = 0.01 % of NaCl in water

Mass % of solute = [Mass of solute in grams / Mass of solution in grams] x 100.

Let us suppose that mass of the solution is 100 g.

Therefore mass of NaCl = 0.01 g

Mass of water = 100-0.01 = 99.99 g.
