To begin with, you should know that in chemistry,concentrationis often expressed in moles per unit volume, usually liters (mol/L) rather than in mass units per liter. The number of grams in 1 mol of a substance can be determined from the molar masses or molecular weights of its constitue...
The number of water molecules present in every formula unit of the ionic compound determines the water of crystallization or water of hydration of the salt. The value of the water of crystallization varies from one salt to another...
