A 14.6 g sample of the bicarbonate of the element X was heated and decomposed to
the oxide of bivalent metal, water and carbon dioxide. Indicate the formula of the
compound, assuming that the volume of CO2 (at STP) was 4.48 dm3.
How would I go about solving this problem? I know that the metal is going to be out of group IIa since it's bivalent but I'm stumped with the rest. Where would you start? Would you calculate the moles of CO2 by doing 4.48 (1/22.4) and then what? Once again I'm not looking for the answer because the answer won't really do me any good. I need to know how to approach these types of problems. Any help will be greatly appreciated.
