2H2S + 3O2 -> 2SO2 +2H2O Starting with 9.2 moles of O2, How many moles of H2O will you produce?

Answer 1

you can use the balanced chemical equation to see what the mole ratio is between the two substances! on this one we have 3 mol O₂: 2 mol H₂O, meaning that the calculation here is

9.2 moles of O₂ x 2 mol H₂O / 3 mol O₂ = 6.13 moles of H₂O being produced in this scenario

Answer 2

2H₂S + 3O₂ = 2SO₂ + 2H₂O

From the reaction we can see,

3 moles of O2 can produce = 2 moles of H2O

1 mole of O2 can produce = 2/3 moles of H2O

9.2 moles O2 can produce = (2/3) x 9.2 moles of H2O

= 6.13 moles of H2O
