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

**Part A**

Barium can be analyzed by precipitating it as BaSO₄ and weighing the precipitate. When a 0.265 g sample of a barium compound was treated with excess H₂SO₄, 8.60×10⁻² g of BaSO₄ formed. What is the percentage of barium in the compound?

**Part B**

What is the percentage of sodium in pure table salt?

Report your answer as a percentage to three significant figures.

**Part C**

An impure sample of table salt that weighed 0.8571 g, when dissolved in water and treated with excess AgNO₃, formed 2.031 g of AgCl. What percentage of NaCl is in the impure sample?
