Each mole of substance A (Molar mass =720 ) required 10 moles of water for complete hydrolysis and gives B,C and D as the hydrolysed product in a molar ratio of 2:3:2. if molecular mass of B is 40 and it contributes 40% of total mass of hydrolysed product then moles of C obtained will be

The equivalent weight of a species if acts as oxidant or reductant should be derived by : Eq. weight of oxidant or reductant = ("Mol. wt. of oxidant or reductant")/{("Number of electrons lost or gained by one"),("moleculae of oxidant or reductant"):} During chemical reactions, equal equivalents of one species react with same number of equivalents of other species giving same number of equivalent of products. However this is not true for reactants if they react in terms of moles. Also Molarity can be converted to normality by multiplying the molarity with valence factor or 'n' factor.
