can u list all the imp formulae regardin equivalent weight!!

Dear Paritosh,

Determine the valence of the compound. The valence refers to how many hydrogen atoms could bond with the compound. It is determined by the relationship between elements in a compound. For NaCl, the valence is 1 because only one hydrogen atom could bond with NaCl. For H2So4, or sulfuric acid, the valence is 2 because two hydrogen atoms bond with sulfate, or So4.

Divide the molecular weight by the valence to calculate the equivalent weight. The equivalent weight of NaCl is 58.443/1 or 58.443

Best Of Luck...!!!!
