Answer:
0.881 kilograms
Explanation:
Mass of 
= 305 g
Molar mass of = 63.546 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 4.8 moles
Since in the formula of 
,
1 mole of copper is present in 1 mole of
So,
4.8 mole of copper is present in 4.8 mole of
Moles of = 4.8 moles
Molar mass of = 183.53 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of = 881 g
Also, 1 g = 0.001 kg
So,
<u>0.881 kilograms of chalcopyrite must be mined to obtain 305 g of pure Cu.</u>
