A solution is prepared by adding 2 g of a substance A to 18 g of water. Calculate the mass per cent of the solute.

Text Solution

Verified by Experts

Mass of solute, A = 2g
Mass of water = 18 g
Mass of solution = 2+18 = 20g
Mass percent of A `=("Mass of A")/("Mass of solution") xx 100`
`=2/20 xx 100 = 10%`
