A sample of $\text{Na}_2\text{CO}_3$ powder with a mass of $3.0\,\text{g}$ is mixed with $50\,\text{cm}^3$ of $1.0\,\text{mol dm}^{-3}$ HCl. The $\text{CO}_2$ collected has a volume of $600\,\text{cm}^3$. $\text{Na}_2\text{CO}_3(s) + 2\text{HCl}(aq) \rightarrow 2\text{NaCl}(aq) + \text{CO}_2(g) + \text{H}_2\text{O}(l)$ $[M_r: \text{Na}_2\text{CO}_3, 106.0]$ Under these same conditions, what volume of $\text{CO}_2$ would be formed if $1.0\,\text{g}$ of $\text{Na}_2\text{CO}_3$ powder were mixed into $50\,\text{cm}^3$ of $1.0\,\text{mol dm}^{-3}$ HCl?
- A$600\,\text{cm}^3$
- B$452\,\text{cm}^3$
- C$226\,\text{cm}^3$
- D$200\,\text{cm}^3$
