What is the mass percent of a solution when 18.6 g of table salt is added to 81.4 g of water?

Mass Percent = mass of solute(g)x100

mass of solution (g)

= 18.6 g x100

18.6 g + 81.4g

= 18.6 g x 100

100g

= 0.186 x 100

= 18.6

The mass percent of the solution is 18.6%

mass percent = (mass solute/100 g solution)*100

[(18.6)/(18.6 + 81.4)]*100 =

(18.6/100)*100 = 18.6%
