A solution contains 80.0 g of sodium chloride and 400.0 g of water. Calculate the NaCl as a mass percentage
Answered by bonjo
total mass of the solution is 400+80 = 480g. mass% of solute = mass of solute/total mass of solution

hope that helps...

Just a slight addition.
mass % = (mass solute/total mass soln)*100 = ?
