For the reaction?

Question

SO2 + O2 → SO3


how many moles of SO3 are produced from the complete reaction of 3.02 moles of SO2 ?

Enter a numeric answer only, no units.

Answer 1

Look at your equation -- to balance it, you need to add a ½ before the O2, so that it looks like this:

SO2 + ½ O2 ===> SO3

So, if one mole of SO2 produces one mole of SO3, then 3.02 moles of SO2 produces . . . . . .?
