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((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 .
