Calculate the masses of water and salt required to prepare a 200 g solution with a salt fraction of 0.25.
| August 3, 2021 | education
The mass of the solution is 200 grams;
To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.
m salt = 200 x 0.25 = 50 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m of water = 200 – 50 = 150 grams;
Check: 150 + 50 = 200;
