Calculate the mass of water required to prepare 60 g of a 10% salt solution.

To prepare 60 g of a 10% salt solution, you need to take a weighed portion of the salt and measure the required amount of water. If in 60 grams of solution salt occupies a mass fraction of 10%, then its mass should be equal to 60 * 10% = 6 grams. The mass of water is 60-6 = 54 grams. Liquid substances are not weighed, but measured with graduated cylinders. The density of water is 1 gram / cm3, therefore, to measure 54 grams of water, you need to measure 54 milliliters of liquid.
