A solution has been prepared by dissolving 5 g of urea in 95 g of water. What is the mass percent of urea in the solution ?

Text Solution

Verified by Experts

Mass percent (Mass %) = `("Mass of solute")/("Mass of solution")xx100`
Mass of urea = 5 g, Mass of water = 95 g
Mass of solution = (5 + 95) = 100 g.
Mass percent of urea = `((5g))/((100g)) xx 100 = 5%`
