Calculate the mass fraction of salt in a solution prepared from 30 grams of salt and 200 grams of water.
| November 22, 2020 | education
The mass fraction is denoted by w and is found by the formula: w = m (in-va) / m (solution) * 100
m (in-va) = m (salt) + m (water) 30 + 200 = 230
Let’s find the Mass fraction according to the first formula: 30/230 * 100≈13%
