Stoichiometry

Stoichiometry is a chemical division that evaluates the quantitative content of the chemical process with the help of the reacting molecules or products taking part in the reaction. The term “stoicheion” in “Stoichiometry”, is an old Greek term for "element" whereas “metron” means "measure".

Question

**Chemical Analysis Problem:**

A 2.85 g sample of NaCl and CaCl₂ was dissolved in water, and an excess of AgNO₃ was added to precipitate all of the chloride ions. The AgCl was collected and dried, and weighed to give 7.20 g of AgCl. How much NaCl and CaCl₂ was in the sample?

**Questions:**

1. ____ g NaCl

2. ____ g CaCl₂

This problem demonstrates the application of stoichiometry in determining the composition of a mixture using precipitation reactions.

**Instructions:**

- Use the known mass of AgCl to calculate the moles of Cl⁻.
- Determine the amount of NaCl and CaCl₂.
- Fill in the blanks with the calculated masses of NaCl and CaCl₂.
