Homework Statement
How many millilitres of oxygen gas are released from heating 5.00 grams of calcium chlorate?
Homework Equations
Ca(ClO3)2→CaCl2+3O2
Ca(ClO3)2 =207.7g
CaCl2=110.98g
O2=22.4 g/L
Mole ratio= 3mol O2/1mol Ca(Clo3)2
The Attempt at a Solution
This is what I have but it is not coming out right and I just can't figure out where I am going wrong. I am having trouble with these kinds of problems.
(207.7 g/ 1 mol Ca(Clo3)2) X (1mol Ca(Clo3)2/3 mol O2) X (22.4 L O2/ 1 mol O2)= 1550.8
(this can't be right the answer is supposed to be 1620)
