Determine how much water and salt is required to obtain 30 g of a 15% salt solution.
First, you need to determine the mass of the salt. We write down the solution.
m (salt) = 30 * 0.15 = 4.5 g.
Therefore, you need 4.5 g of salt.
Next, we find the mass of water.
m (H2O) = 30 – 4.5 = 25.5 g.
This means that water will need 25.5 g.
