| The mass fraction of a substance (in this case, salt) can be found by the following formula: w = m (in) / m (solution), where w is the mass fraction of the substance, m (in) is the mass of the substance, m (solution ) Is the mass of the solution.

In our case, m (in) = 10 grams, m (solution) = 50 grams.

We calculate: 10/50 = 0.2

Answer: the mass fraction of salt in this solution is 0.2.
