There is a 50g-5% salt solution. What is the mass of the salt solution in it?

Let’s transform the formula:
W (in-va) = m (in-va) / m (solution) • 100%.
And we will find the mass of salt in this solution.
m (in-va) = W (in-va) • m (solution) / 100% = 5% • 50 g / 100% = 2.5 g.
Accordingly, the mass of water is.
m (water) = 50 g – 2.5 g = 47.5 g.
