arbon dioxide gas. saturated with water vapor, can be produced by the addition of aqueous acid to calcium carbonate.

msp;  ${\text{CaCO}}_{\text{3}}\left(s\right)+{\text{2H}}^{+}\left(aq\right) {\text{Ca}}^{\text{2}+}\left(aq\right)+{\text{H}}_{\text{2}}\text{O}\left(l\right)+{\text{CO}}_{\text{2}}\left(g\right)$

w many moles of ${\text{CO}}_{\text{2}}\left(g\right)$, collected at $\text{6}0.°\text{C}$and $\text{774}$torr total pressure, are produced by the complete reaction of $\text{1}0.0\text{ g}$of ${\text{CaCO}}_{\text{3}}$with acid? What volume does this wet ${\text{CO}}_{\text{2}}$occupy? What volume would the ${\text{CO}}_{\text{2}}$occupy at $\text{774}$torr if a desiccant (a chemical drying agent) were added to remove the water? (The vapor pressure of water at $\text{6}0.°\text{C}$is $\text{149}.\text{4 mm Hg}$.)
