Question

Mass of x /Mass of solution x 100
5 g /5 g of x + 18 g of water x 100 = 21.74%
explain.​

Answer 1

Answer:

Mass percent of solute =

mass of solution

mass of solute

×100

Mass of solute = 2 g

Mass of solvent = 18 g

Mass of solution = 20 g

∴ Mass percent of solute =

20

2

×100

=10%

Hence, option B is correct
