Step-by-step explanation:
Answer: 36 moles oxygen
Step-by-step explanation:
C10H8 + 12O2 ====》 10CO2 + 4H2O
From the equation of the reaction,
1 mole of napth requires 12 moles of O2
3 moles of napth would require x moles O2
X = (3 * 12) / 1
X = 36 moles of oxygen.
Therefore 3 moles of naphtalene (C10H8) would require 36 moles of oxygen
