Problem- Small quantities of oxygen can be prepared in the laboratory by heating potassium chlorate, KClO3(s). The equation for the reaction is
2KClO3 ---> 2KCl + 3O2
Calculate how many grams of O2(g) can be produced from heating 93.9 grams of KClO3(s).
Please explain above problem in step by step manner so I can easily understand it
