Question

if 20 g of salt is present in 220 g of a solution.what is the concentration of the solution? ​

Answer 1

mass of solute = 20g

mass of solution = 220g

by mass percentage of solute=mass of solute/ mass of solution x 100

20/220 x 100

1/11 x 100

9%

Answer 2

Answer:

salt = 20g

solution = 220 g

concentration = amount of solute/solution ×100

=( 20/220)×100

= 1/11×100

= 100/11

= 9.09%
