Question

5g of solute dissolved in 45g of water.what is the percentage by Mass of solution

Answer 1

the concentartion is-
Mass of solute=5g
Mass of solvent=5+45=50g
Therefore concentartion is 5/50*100%
i.e. 10%
hope you understood.

Answer 2

Answer:

10% is the percentage by Mass of solution

Explanation:

Mass of solute = 5 g

Mass of solvent that is water = 45 g

Total mass of solution =  45g + 45 g = 50 g

$Mass\%=\frac{5 g}{50}\times 100=10\%$

10% is the percentage by Mass of solution
