Calculate the mass fraction of the solute if 68 g of water was dissolved in 12 g of salt.
| November 22, 2020 | education
The mass fraction of the solute is calculated by the following formula: w = m (solute) / m (solution) * 100%
The mass of the solution will be equal to the sum of the mass of water of the solute:
68 + 12 = 80 grams of solution.
Substitute the values into the above formula: 12/80 * 100 = 15%
