If 16 mol of oxygen were reacted with excess hydrogen gas, how many moles of water would be produced?

1) first, we need a balanced equation

2H₂ + O₂ ---> 2H₂O

2) we use the mole-to-mole ratio to convert the moles of oxygen to moles of water.

ratio > 1 mol O₂= 2 mol H₂O (based on the coefficients)

16 mol O₂= 2 x 16 mol H₂O
16 mol O₂ = 32 mol H₂O

Ijust took the quiz. their is no coefficient needed. : )
