1.	How is mole concept applied to ionic compounds illustrate with an example
Answer» As an example, consider sodium chloride, NaCl, the chemical name for common table salt. Sodium chloride is an ionic compound composed of sodium cations, Na+, and chloride anions, Cl−, combined in a 1:1 ratio. The formula mass for this compound is computed as 58.44 amu\xa0Aluminum sulfate, Al2(SO4)3,The formula for this compound indicates it contains Al3+\xa0and SO42−ions combined in a 2:3 ratio. For purposes of computing a formula mass, it is helpful to rewrite the formula in the simpler format, Al2S3O12.\xa0
