How many moles of HbO2 are produced from 8.43 moles of oxygen gas?

Answer 1

I see from subsequent posts that the product is HBO₂, made from B₂H₆ apparently in the reaction B₂H₆ + 2 O₂ --> 2 HBO₂ + 2 H₂. So just use the mole ratios from the balanced reaction to convert: (8.43 mol O₂) * (2 mol HBO₂ /2 mol O₂) = 8.43 moles of HBO₂.
