Ferrochrome, an iron chromium alloy used...

Ferrochrome, an iron chromium alloy used in making stainless steel, is produced by reducing chromite `(FeCr_(2)O_(4))` with coke :
`FeCr_(2)O_(4)(s) + 4C (s) rarr underset("Ferrochrome")(underbrace(Fe(s) + 2Cr(s))) + 4CO(s)`
(i) How many kilograms of chromium can be obtained by the reaction of 236 kg of chromite with an excess of coke ?
(ii) How many litres of CO at `25^(@)`C and 740 mm Hg are obtained as a by-product ?
