9.90. Acid precipitation dripping on limestone produces carbon dioxide by the following reaction:
\[
\mathrm{CaCO}_{3}(s)+2 \mathrm{H}^{+}(a q) \rightarrow \mathrm{Ca}^{2+}(a q)+\mathrm{CO}_{2}(g)+\mathrm{H}_{2} \mathrm{O}(\ell)
\]
Suppose that 8.6 mL of \( \mathrm{CO}_{2} \) are produced at \( 15^{\circ} \mathrm{C} \) and 760 mmHg .
a. How many moles of \( \mathrm{CO}_{2} \) are produced?
b. How many milligrams of \( \mathrm{CaCO}_{3} \) are consumed?
