Which reactant runs out?

Marble chips react with hydrochloric acid: $\text{CaCO}_3 + 2\text{HCl} \rightarrow \text{CaCl}_2 + \text{H}_2\text{O} + \text{CO}_2$. You start with $25\ \text{g}$ of marble and $14.6\ \text{g}$ of hydrogen chloride. You will find the limiting reagent, the carbon dioxide formed and what is left over.

The idea. Change grams to moles. Divide each by its coefficient: the smallest share runs out first, and that share sets the amount of every product.

Your tasks.

1. Fill moles with the moles of each reactant.
2. Set limiting to the name of the limiting reagent.
3. Set co2_g to the mass of carbon dioxide formed, in grams.
4. Set left_g to the mass of the excess reactant left over, in grams.
