When calcium carbonate, $\text{CaCO}_3$, is added to dilute hydrochloric acid, carbon dioxide is formed. The reaction equation is given below. The relative formula mass of calcium carbonate is $100$. $\text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2$ A sample of $10\,\text{g}$ of calcium carbonate is reacted with excess dilute hydrochloric acid. What mass of carbon dioxide is formed?
- A$2.2\,\text{g}$
- B$2.8\,\text{g}$
- C$4.4\,\text{g}$
- D$44\,\text{g}$
