How many moles of carbon monoxide gas are produced from the reaction of 5.00 moles of SnO2(s) with 9.00 moles of carbon according to the equation below?



SnO2(s) + 2C(s) → Sn(s) + 2CO(g)

Question 28 options:

4.50 mol


9.00 mol


18.0 mol


5.00 mol


7.50 mol

1 answer

5 mols SnO2 reqires 10 mols C
but we only have 9
9 mols C require 4.5 mols SnO2
and yield 9 mols CO with half a mol SnO2 left over
The 10 mols CO will kill you.
