Determine the mass of acetic acid in 100 g of a 25% solution.
| February 8, 2021 | education
The mass of the solute (in this case, acetic acid) in the solution is found by the formula:
m in-va = w in-va × m solution: 100%,
Where:
m in – the mass of acetic acid, g,
w in-va – mass fraction of a substance in a solution,%,
m solution – mass of solution, g.
m in-va = w in-va × m solution = 25% × 100 g: 100% = 25 g of acetic acid contained in this solution
