Calculating grams from chemical reaction

Question

How many grams of oxygen gas are produced when 2.43x10^-4 g of KClO3 are completely reacted according to the following chemical reaction: 2KClO3(s)=2KCl(s)+3O2(g)

Answer 1

1. Calculate the g/mol of KClO3 and the g/mol of O2
2. Use the g/mol of KClO3 in dimensional analysis to convert the g of KClO3 to mol of KClO3
3. Continue with the stoichiometric ratio of 2 mol of KClO3 to 3 mol of O2 from the balanced reaction to determine mol of O2
4. Use the g/mol of O2 to convert mol of O2 to g of O2
