If 2.50 metric tons of bornite is reacted with excess o2 and the process has an 86.3% yield of copper, what mass of copper is produced?

Answer : The mass of copper produced is,

Explanation :  Given,

Mass of bornite =

conversion used :

Molar mass of = 342.678 g/mole

First we have to calculate the moles of .

Now we have to calculate the moles of .

The balanced chemical reaction will be,

From the balanced reaction, we conclude that

As, 2 moles of react to give 6 moles of

So, 7295.48 moles of react to give moles of

Now we have to calculate the mass of

The theoretical yield of  = 1390795.716 g

The actual yield of  = ?

Now we have to calculate the actual yield of .

Therefore, the mass of copper produced is,

idk i’m struggling too

the answer is barium and copper bromide
