Question#31-32, I not sure and don’t know how to do,
LUCKY_DIMON [66]

Answer: 30. 7 moles SO3

31. 3 moles SO2 and 3 moles SO3

Explanation: To solve for this problem use the mole ratio of the substances involved in the reaction.

Solution for number 30:

3.5 moles O2 x 2 moles SO3 / 1 mole O2

= 7 moles SO3

31. 192 g SO2 x 1 mole SO2 / 64 g/ mol SO2

= 3 moles SO2

3 moles SO2 x 2 moles SO3 / 2 moles SO2

= 3 moles SO3
