50 grams of solution was evaporated and 5 grams of salt were obtained. Calculate the mass fraction of salt

If, when evaporating 50 g of the solution, 5 g of salt remained, then 45 g was water.
We find the mass fraction of salt in the solution according to the formula:
W (salt) = m (salt) / m (solution) • 100% = 5/50 • 100% = 10%.
Accordingly, 5 g of salt in 50 g of solution is a 10% salt solution.
