A solution is prepared by dissolving 2g of substance A in 18g of water. calculate the mass percentage of solute?

Text Solution

Verified by Experts

We are given that Mass of substance A= 8g
Mass of water= 18g
We know that, Mass percent of `A= ("Mass of A")/("Mass of solution") xx 100 (8g)/(8g + 18g)xx 100= (8g)/(26g)xx 100= 30.76%`
