If you have 17 moles of O2, how many moles of B2H6 will you need for this reaction?

Answer 1

Even though you didn't supply the equation, I'll assume it is as follows:

B₂H₆ + 3O₂ → 2HBO₂ + 2H₂O ... balanced equation

Using dimensional analysis, you can easily solve for the moles of B₂H₆ needed to react with 17 moles O₂:

17 moles O₂ x 1 mol B₂H₆/3 mol O₂ = 5.7 moles B₂H₆ needed

Answer 2

Hi Griffin,

You didn't give the reaction!

I need to know the chemical reaction to be able to answer
