Consider the reaction below. 2H2 + O2 mc015-1.jpg 2H2O How many moles of water are produced from 13.35 mol of oxygen?
Leokris [45]

Answer: 26.7 moles

Explanation: 2H_2+O_2\rightarrow 2H_2O

As can be seen from the balanced chemical equation 2 moles of hydrogen combine with 1 mole of oxygen to give two moles of water.

1 mole of oxygen give = 2 moles of water.

Thus 13.35 moles of oxygen give=\frac{2}{1}\times 13.35=26.7moles of water.
