1.	1.60 g of a metal were dissolved in HNO_3 to prepare its nitrate. The nitrate was strongly heated when 2.0 g of the metal oxide was obtained. Calculate the equivalent weight of the metal.
Answer» Solution :Mass of the METAL taken = 1.60 g Mass of OXIDE formed = 2.0 g `THEREFORE` Mass of oxygen that combined with 1.60 g of the metal `=2.0- 1.60 = 0.40 g` `therefore`Equivalent weight of the metal `=("Mass of the metal")/("Mass of oxygen") xx 8 = 1.60/0.40xx 8 = 32`
