A blast furnace is charged with magnetite pellets. It produces a $4$

wt$\%$ C pig iron. $470$ kg of carbon $($as coke$)$ and $370$ kg of oxygen $($as

air blast$)$ are supplied to the furnace per ton of product Fe$.$ Calculate

analytically:

i$.$ The composition $($including N$2)$ of the top gas from this

furnace; $(10)$

ii$.$ The volume of top gas per kg mole and per ton of product Fe$.$
