How many moles of O2 are required if 12 moles of CuFeS2 are consumed?

matrenka [14]

Answer:- 30 moles of oxygen are required if 12 moles of $CuFeS_2$ are consumed.

Solution:- The given balanced equation is:

$2CuFeS_2+5O_2\rightarrow 2Cu+2FeO+4SO_2$

From this balanced equation, there is 2:5 mol ratio between $CuFeS_2$ and $O_2$ .

We are asked to calculate the moles of $O_2$ required to react with 12 moles of $CuFeS_2$ .

It's a mol to mol conversion and the set up for this would be as:

$12 mol CuFeS_2(\frac{5 mol O_2}{2 mol CuFeS_2})$

= $30 mol O_2$

So, 30 moles of oxygen are required to react with 12 moles of $CuFeS_2$ .
