How many grams of table salt and water do you need to take to prepare 650g of a 50% salt solution?
| September 9, 2021 | education
Determine the mass of salt required to prepare 650 g of a 50% solution:
W (in-va) = m (in-va) / m (solution) • 100%.
The mass of salt will be equal to:
m (salt) = W (salt) • m (solution) / 100% = 50 • 650/100 = 325 g.
The mass of water is:
m (H2O) = m (solution) – m (salt) = 650 – 325 = 325 g.
So salt and water should be taken in a 1: 1 ratio.
