What mass of salt and what volume of water is contained in 150g of 25% sodium chloride solution ^ 2?

The mass of the solution is 150 grams;

To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.

m salt = 150 x 0.25 = 37.5 grams;

To find the mass of water, subtract the mass of salt from the mass of the solution:

m of water = 150 – 37.5 = 112.5 grams;

The density of water is 1 gram / cm3.

Therefore, 112.5 grams of water takes up a volume of 112.5 milliliters.

Check: 180 + 20 = 200;
