Question

1.08 g of a metal oxide on being reduced gives 1 g of metal. Calculate the eq. weight of the metal.

Answer 1

Answer:

here we use the concept that equivalents of metal oxide = equivalents of metal

eq.of metal oxide=1.08/(E+8)  where E=eq. weight of METAL   // note eq. weight of oxygen in metal oxide is 8

eq. of metal=1/E

now equating these we get 

1.08/(E+8)=1/E  which gives E=100 HENCE THE ANS.....
