A solution had been prepared by fisolving 5g of urea in 95g of water. What is the mass percent of urea in the solution

Answer 1

Here weight of solute(urea) is 5gm

Weight of solvent(water) is 95gm

Mass percentage =

{weight of solute÷weight of solution(solvent+solute) }×100

[5÷(95+5)]×100

[5÷100]×100

Mass percentage of urea=5%
