What mass of salt and volume of water should be taken to prepare 100 g of 5% sodium chloride solution?
September 19, 2021 | education
| The mass of the solution is 100 grams;
To find the mass of salt, it is necessary to multiply its mass fraction by the mass of the solution.
m salt = 100 x 0.05 = 5 grams;
To find the mass of water, subtract the mass of salt from the mass of the solution:
m of water = 100 – 5 = 95 grams;
Check: 95 + 5 = 100;
