The reaction taking place is:
4 Fe + 3 O2 —> 2 Fe2O3
mol of O2 required = (3/4)*moles of Fe reacted
= (3/4)*0.376 mol
= 0.282 mol
we have:
P = 1.0 atm
n = 0.282 mol
T = 0.0 oC
= (0.0+273) K
= 273 K
we have below equation to be used:
P * V = n*R*T
1 atm * V = 0.282 mol* 0.0821 atm.L/mol.K * 273 K
V = 6.32 L
Answer: 6.32 L
