1.	2.1 g of metal carbonate on thermal decomposition gave 1 g of metal oxide as residue. Determine theequivalent weight of metal.
Answer» Solution :Let the EQUIVALENT weight of metal=x Equivalent weight of metal oxide =x+8 Equivalent weight of metal CARBONATE =x+30 When weight RATIO is related to equivalent weight ratio for two substances `(W_(i))/(W_(2))=(E_(1))/(E_(2)), (2.1)/(1)=(x+30)/(x+8)` SOLVING , x = 12 Equivalent weight of metal = 12
