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,

since electrons are negative the answer is neagtaive

explanation:

two years ago, when picking flowers in the mountains back of yosemite valley, i found a book. it was blotted and storm-beaten; all of its outer pages were mealy and crumbly. the paper seemed to dissolve like the snow beneath which it had been buried, however; many of the inner pages were well preserved. and although all were more or less stained and torn, whole chapters were easily readable. this is the condition of the great open book of yosemite glaciers today; its granite pages have been torn and blurred by the same storms that wasted the castaway book.
