Determine the masses of water and nitric acid contained in a 1.5 kg solution with a mass fraction of this acid of 20%.
September 1, 2021 | education
| The mass of the acid solution is 1500 grams;
To find the mass of the acid, it is necessary to multiply its mass fraction by the mass of the solution.
m acid = 1500 x 0.2 = 300 grams;
To find the mass of water, you need to subtract the mass of the acid from the mass of the solution:
m of water = 1500 – 300 = 1200 grams;
The density of water is 1 gram / cm3. To prepare this solution, you need to measure out 1200 milliliters of water.
