B. An experiment on the
carbonate of a divalent metal, M, was carried out by a student:-
A dry, empty evaporating dish was weighed and then it was weighed again with some carbonate of metal, M. in it. The dish and its content were then heated strongly until there was nd further change. What left in the dish then was the oxide of the metal, M. The whole thing was allowed to cool and weighed again. The results obtained
were as follows. Mass of dish mass of dish+carbonate
=42.309
