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".

Use the molar mass of 02, which has the units g/mol, as a conversion factor between its mass and the number of moles. Then use the coefficients of the balanced
chemical equation as a mole-to-mole conversion factor to calculate the number of moles of KO2. Finally, convert the number of moles of KO2 to mass using its molar
mass as a conversion factor.
