We have 6 grams of salt and this is 8% of the whole compound, which means that 100% of the compound will weigh X. Add the proportion: 6 grams – 8%, X grams – 100%, hence X = 6 * 100/8 = 75 grams. We have a solution weighing 75 grams where there is 6 grams of salt, which means there is water: 75 – 6 = 69 grams of water.
