Close. You need to find the mass percentage of oxygen _atoms_ in the KClO3 molecule.
NB: There are 3 atoms of O in every molecule of KClO3.
KClO3: 122.5498 g/mole
Contains:
O: 3 * 15.99943 g/mole
=====================
Mass percentage: 39.1664%
Calculate the theoretical mass percent of oxygen in KClO3.
here is the my mass percentage of 02 25gKCl03/30.0gKCl03=0.61%02.
