Question

Determine the number of moles of sulfur trioxide produced when 3.5 moles of oxygen gas is consumed in the reaction

Answer 1

Hello there.

Determine the number of moles of sulfur trioxide produced when 3.5 moles of oxygen gas is consumed in the reaction

7 mol SO3

Answer 2

The balanced chemical reaction would be:

2SO2 + O2 = 2SO3

We are given the amount of oxygen to be used. We calculate as follows:

3.5 moles O2 ( 2 mol SO3 / 1 mol O2 ) = 7 mol SO3 is produced from the reaction.

Hope this answers the question. Have a nice day.
