Chlorine atoms cause chain reactions in the stratosphere that destroy ozone that protects the Earth's surface from ultraviolet radiation. The chlorine atoms come from chlorofluorocarbons, compounds that contain carbon, fluorine, and chlorine, which were used for many years as refrigerants. One of these compounds is Freon-12, CF2Cl2. If a sample contains 1.0 × 10-9 g of Cl, how many grams of F should be present if all of the F and Cl atoms in the sample came from CF2Cl2 molecules?

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".
