How many grams of salt and water do you need to take for preparation: a) 120 g of 20% solution b) 250 g of 25% solution?
a) 120 g of solution contains 120 * (20% * 100%) = 120 * 0.2 = 24 g of in-va, to which 120 – 24 = 96 g (ml) of water must be added.
b) 250 g of solution contains (25%: 100%) * 250 = 0.25 * 250 = 62.5 g of salt. To it you need to add 250 – 62.5 = 187.5 g (ml) of water.
