Calculate the mass fraction of solutes if 12 g of salt was dissolved in 88 g of water.

The solution consists of two components: water weighing 88 grams and salt weighing 12 grams.

The mass of the solution is equal to the sum of their masses:

m solution = 12 + 88 = 100 grams.

To find the mass fraction of salt, we divide the mass of salt by the mass of the solution:

C = m salt / m solution = 12/100 = 0.12 = 12%;
