| Determine the mass of salt in the solution.
To do this, multiply its mass fraction by the weight of the solution.
M salt = 400 x 0.125 = 50 grams;
Let’s calculate the weight of water in the same way.
To do this, multiply its mass fraction by the weight of the solution.
M water (solvent) = 400 x 0.875 = 350 grams;
Let’s check:
50 + 350 = 400;
