Question

At STP \(x\) g of a metal hydrogen carbonate (MHCO$_3$) (molar mass \(84 \, {g/mol}\)) on heating gives CO$_2$, which can completely react with \(0.02 \, {moles}\) of MOH (molar mass \(40 \, {g/mol}\)) to give MHCO$_3$. The value of \(x\) is:

• A. \(67.2\)
• B. \(33.6\)
• C. \(11.2\)
• D. \(22.4\)

Hint:

When solving stoichiometry problems, always verify the mole ratios and ensure unit consistency throughout calculations. Keep track of each reaction step and verify with correct chemical equations to avoid calculation mistakes.
