For the reaction?

Question

SO2 + O2 → SO3


how many moles of SO3 are produced from the complete reaction of 1.16 moles of O2 ?

Enter a numeric answer only, no units.

Answer 1

1.55



Solution:
the balance equation is
SO2 + O2 → 1.33SO3

hence, if you have 1.16 moles of O2, by ratio and proportion, you would produce 1.55 moles SO3 if it undergoes a complete reaction.

Answer 2

Balance equation 2SO2 + O2 -> 2SO3

(1.16moles O2) ( 2 moles SO3/ 1 Mole O2) = 2.32 moles SO3


answer = 2.32
