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
<h3>Molar mass of CuFeS₂ =? </h3>
Molar mass of CuFeS₂ = 63.5 + 56 + (32×2)
= 63.5 + 56 + 64
= 183.5 g/mol
Thus,
<h3>1 mole of CuFeS₂ = 183.5 g</h3>
Next, we shall convert 183.5 g to ton. This can be obtained as follow:
<h3>907185 g = 1 ton</h3>
Therefore,
183.5 g = 183.5 / 907185
<h3>183.5 g = 2.0227×10¯⁴ ton</h3>
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 = = 125574726850.25 g of Cu
Thus, 400000 ton of CuFeS₂ contains 125574726850.25 g of Cu
