Iron chloride is produced by heating iron in chloride gas. The equation for the reaction is: 2Fe+3Cl2²-->2FeCl³ Calculate the volume of chlorine needed to react with 14 g of iron. You should calculate: the number of moles of iron used the number of moles of chlorine that react with 14 g of iron the volume of chlorine needed. Relative atomic mass (Ar): Fe = 56 The volume of 1 mole of gas = 24 dm³
