Zinc oxide reacts with carbon to produce zinc. The equation for the reaction is: \

\text{ZnO} + \text{C} \rightarrow \text{Zn} + \text{CO}{\char"24}$ Calculate the percentage atom economy for obtaining zinc from this reaction. Use the equation: \

\text{Percentage atom economy} = \frac{A_{\text{r}}\text{ of Zn}}{M_{\text{r}}\text{ of ZnO} + A_{\text{r}}\text{ of C}} \times 100{\char"24} Relative atomic masses (\A_{\text{r}}$): $\text{C} = 12$, $\text{Zn} = 65$. Relative formula mass ($M_{\text{r}}$): $\text{ZnO} = 81$.
