Answer:
0.693kg of CuFeS2 is needed to produce 240 grams of Cu.
Explanation:
In 1 mole of CuFeS2 is associated 1 mole of Cu.
Molar mass of CuFeS2 = 183.5 g/mol
Molar mass of Cu = 63.5g/mol
No of moles of copper present in 240g of chalcopyrite = 240/63.5 = 3.779moles
we know
1 mole of Cu → 1 mole of CuFeS2
in 3.779 moles of Cu → 3.779 moles of CuFeS2
3.779 moles of CuFeS2 = 3.779 * 183.5 = 693.45grams
CuFeS2 in kg = 0.693kg
