Epsom salts, a strong laxative used in veterinary medicine,is a hydrate, which means that a certain number of watermolecules are included in the solid structure. The formulafor Epsom salts can be written as MgSO4 # xH2O, where xindicates the number of moles of H2O per mole of MgSO4.When 5.061 g of this hydrate is heated to 250 °C, all the waterof hydration is lost, leaving 2.472 g of MgSO4. What isthe value of x?

Mole Concept

Mole concept is a method to determine the amount of any substance that consists of some elemental particles using a grouping unit called ‘mole’. The mole concept enables one to handle the large amount of small elementary particles. The mole concept can be used in many calculations related to mole calculation, molar amount, mole ratio, and so on, which are significant in chemistry.
