Question

a solution contain 40g of common salt in 100g of water .calcuate the concentrate in term of mass by mass percentage of the solution?
​

Answer 1

Explanation:

Mas of common salt (solute)=40 g

Mass of water (soluted) =320 g

mass of solution=320+40

=360 g

concentration of solution=

M mass of solute/mass of solution×100

40/360 ×100=11.11%

Hence, the concentration of the solution is 11.11%
