Did I do this correctly or do I need to try again?

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%
