Question

What is the mass-percent of a KCl solution of 25 g of KCl is dissolved in 125 g of water.

17%

5 %

50%

25%

Answer 1

The answer to your question is 17 %

Step-by-step explanation:

Data

Solute = 25 g

Solvent = 125 g

Formula

`mass percent = (mass of solute)/(mass of solution) x 100`

Substitution

`mass percent = (25)/(125 + 25) x 100`

Simplification and result

`mass percent = (25)/(150) x 100`

mass percent = 17%
