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 .
