Would it affect your calculation of theoretical yield? Could it affect your measurement of actual yield? Possible error "Wet" CaCl2 2H2O Had "difficulty" with the balance Didn't use/read the pump correctly when measuring Na2CO3(aq) (added more or less than you thought) Molarity on the Na2CO3(aq) is incorrect Let the mixture boil on the hotplate Had fine (small) crystals rather than large ones after digesting the precipitate Had a hole in your filter paper, resulting in a cloudy liquid when filtering Didn't heat the solid in the oven long enough

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".
