Answer:
The answer to your question is 6 moles of oxygen
Explanation:
Data
methanol = CH₃OH
number of moles = 4
moles of oxygen = ?
Process
1.- Write and balance the chemical reaction
2CH₃OH + 3O₂ ⇒ 2CO₂ + 4H₂O
Reactants Elements Products
2 Carbon 2
8 Hydrogen 8
8 Oxygen 8
2.- Calculate the moles of oxygen
2 moles of methanol ----------------- 3 moles of oxygen
4 moles of methanol ------------------ x
x = (4 x 3) / 2
x = 12/2
x = 6
