Moles of Iron : 1.01
Further explanation
Given
Reaction
Fe2O3 + 3CO → 2Fe + 3CO2
34 liters of CO
Required
moles of Iron
Solution
Assumed at STP
Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters / mol.
so for 34 L :
= 34 : 22.4
= 1.518 moles
From the equation, mol Fe :
= 2/3 x moles CO
= 2/3 x 1.518
= 1.01 moles
