1.	0.548 g of the metal reacts with dilute acid and liberates 0.0198 g of hydrogen at S.T.P. Calculate the equivalent mass of the metal.
Answer» Solution :0.548 g of the METAL DISPLACES 0.0198 g of hydrogen The mass of the metal which will DISPLACE 1.008 g of hydrogen ` = (1.008 xx 0.548)/( 0.0198)g` of metal The equivalent mass of the metal `=27.90 g"equiv"^(-1)` .
