Lithium chlorate is decomposed with heat to give lithium chloride and oxygen gas. If 2.23g of lithium chlorate is decomposed, how many milliliters of oxygen are released at stp?

Answer 1

write the balanced equation

2LiCl03>2LiCl + 3O2

2.23 g of liCl03:figure moles of LiCl03

so you will get 1.5 times those moles of O2. Multply by 22.4 to get liters, then a 1000 to get milliliters.
