400000 ton of CuFeS₂ contains 125574726850.25 g of Cu
We'll begin by calculating the mass of 1 mole of CuFeS₂. This can be obtained as follow:
Molar mass of Copper (Cu) = 63.5 g/mol
Molar mass of Iron (Fe) = 56 g/mol
Molar mass of Sulphur (S) = 32 g/mol
Molar mass of CuFeS₂ = 63.5 + 56 + (32×2)
= 63.5 + 56 + 64
= 183.5 g/mol
Thus,
Next, we shall convert 183.5 g to ton. This can be obtained as follow:
Therefore,
183.5 g = 183.5 / 907185
Thus, we see that 2.0227×10¯⁴ ton of CuFeS₂ contains 63.5 g of Cu.
Finally, we shall determine the mass of Cu in 400000 tonnes of CuFeS₂. This can be obtained as follow:
2.0227×10¯⁴ ton of CuFeS₂ contains 63.5 g of Cu.
Therefore,
400000 ton of CuFeS₂ will contain = [tex]\frac{400000 * 63.5}{2.0227*10^{-4} }[/tex] = 125574726850.25 g of Cu
Thus, 400000 ton of CuFeS₂ contains 125574726850.25 g of Cu
