1 ~g of a solute is added to 18 ~g of water. In this aqueous solution, what is the mass per cent of the solute?

Options

A2 %
B5 %
C1 %
D10 %

Correct answer

B. 5 %

Step-by-step solution

Mass % of solute = Mass of solute Mass of solution 100 Mass of solute =1 ~g Mass of solvent =18 ~g Mass of solution =1+18=19 ~g Mass % of solute = 1 19 100 =5.3=5 % Hence, the correct option is (2).
