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

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

5%

Explanation:

Mass percent (Mass %) = `"Mass of solute"/"Mass of solution" xx 100`

Mass of urea = 5 g, Mass of water = 95 g

Mass of solution = (5 + 95) = 100 g

Mass percent of urea = `((5  g))/((100  g)) xx 100` = 5%
