Question

How many moles of oxygen are required to react with methanol in order to produce 13 moles of formaldehyde?

Answer 1

6.5 moles of Oxygen are required

Step-by-step explanation:

Based on the reaction:

CH3OH + 1/2 O2 → CH2O + H2O

1 mole of methanol reacts with 1/2 moles O2 to produce 1 mole of formaldehyde and 1 mole of water.

Thus, to produe 13 moles of formaldehyde, CH2O, are needed:

13 moles CH2O * (1/2mol O2 / 1mol CH2O) =

6.5 moles of Oxygen are required
