A polyvalent metal weighing 0.1 g and having atomic mass 51.0 reacted with dil.

\text{H}_2\text{SO}_4

to give 43.9 mL of

\text{H}_2

at STP. The solution containing the metal in the lower oxidation state was found to require 58.8 mL of 0.1N

\text{KMnO}_4

for complete oxidation. What are valencies of metal?
