|(experimental value) - (theoretical value)| / theoretical value * 100%?
Mass with 0.1 grams MNO2 = 53.300 grams + 20 g KClO3 = 73.300g, after burning so only KCl remained = 65.467 grams
I got 39%
Calculate the percent error in the experiment using the experimental and theoretical values of the mass percent of oxygen. The percent error is defined as
