Question

equivalent mass of the following acid....h3po4(m/3)​

Answer 1

Answer:

Definition of equivalent mass : Equivalent mass is a term which has been used in several contexts in chemistry. In its most general usage, it is the mass of one equivalent, that is the mass of a given substance which will supply or react with one mole of hydrogen cations H+ in an acid–base reaction.  

H3PO4 has 3 H atoms /molecule, therefore the equivalent mass id determined by dividing the molar mass by 3  

Molar mass H3PO4 = 97.9953 g/mol  

Equivalent mass = 97.9953/3 = 32.7g/eq
