How many grams of salt and water are needed to prepare 250 g of a 2% solution of this salt?
| April 8, 2021 | education
Determine the mass of salt in solution based on the formula for the percentage concentration:
W (in-va) = m (in-va) / m (solution) • 100%.
The mass of salt will be equal to:
m (salt) = W (salt) • m (solution) / 100% = 2 • 250/100 = 5 g.
The mass of water required to prepare the solution:
m (water) = m (solution) – m (salt) = 250 – 5 = 245 g.
