Question

A solution contains 40 g of common salt in 320 g of water. Calculate the concentration in terms of mass of mass percentage of the solution.

Answer 1

Mass of solute (salt)=40 g
Mass of solvent (water)=320 g
We know,
Mass of solution =Mass of solute +Mass of solvent
`=40g +320g`
=360 g
Mass percentage of solution
`=("Mass of solute ")/("Mass of solution ")xx100`
`(40)/(360)xx100=11.1%`
