| **Mixed 200 g of a solution with a mass fraction of calcium chloride 25% and 400 g of a solution with a mass fraction of 50%. Calculate the mass fraction of calcium chloride in the resulting solution.**

The weight of the resulting solution will be equal to the sum of the masses of the two initial solutions.

M = 200 + 400 = 600 grams;

The mass of salt in the first solution is 200 x 0.25 = 50 grams;

The mass of salt in the second solution is 400 x 0.5 = 200 grams;

The mass of salt in the resulting solution will be 50 + 200 = 250 grams;

The salt concentration in the new solution will be 250/600 = 0.417 = 41.7%;
