I understand the beginning but I get lost near the end of converting the moles of CaCl2 to grams.
**Chemical Reaction of Calcium Carbonate and Hydrochloric Acid**

When calcium carbonate is added to hydrochloric acid, the products formed are calcium chloride, carbon dioxide, and water. The chemical reaction is represented by the equation:

\[ \text{CaCO}_3(s) + 2 \text{HCl}(aq) \rightarrow \text{CaCl}_2(aq) + \text{H}_2\text{O}(l) + \text{CO}_2(g) \]

**Problem Statement**

Given the following scenario: How many grams of calcium chloride will be produced when 26.0 grams of calcium carbonate is combined with 14.0 grams of hydrochloric acid?

**Solution**

- The mass of \(\text{CaCl}_2\) produced is indicated as 320 grams.

**Excess Reactant**

- The reactant in excess is highlighted:
  - \(\text{HCl}\) (selected)
  - \(\text{CaCO}_3\) (not selected)

**Additional Information**

At the bottom of the content, there is a source and publisher citation:

- **Question Source:** MRG - General Chemistry
- **Publisher:** University Science Books

This example illustrates a stoichiometry problem where the goal is to identify the excess reactant and calculate the mass of a product formed from given masses of reactants.

Expert Solution
Step 1

The balanced reaction taking place is given as,

Chemistry homework question answer, step 1, image 1

Given : Mass of CaCO3 taken = 26.0 g

And mass of HCl taken = 14.0 g

Molar mass of HCl = Atomic mass of H + Atomic mass of Cl = 1 + 35.5 = 36.5 g/mol

And molar mass of CaCO3 = Atomic mass of Ca + Atomic mass of C + Atomic mass of O X 3 = 40 + 12 + 16 X 3 = 100 g/mol
