Answer:
= 6.0 moles
Explanation:
The equation for the reaction is;
2 CH3OH + 3 O2 → 2 CO2 + 4 H2O
We are given 4.0 moles of CH3OH.
From the reaction; 2 moles of CH3OH requires 3 moles of O2,
Therefore; moles of Oxygen will be;
= 4.0 moles × 3/2
= 6.0 moles
Therefore; 6.0 moles of Oxygen gas are required to react completely with 4.0 moles CH3OH.
