Answer:
Given:
Moles of C =
12
12
=1
Moles of O
2
=
32
20
=0.625
Reaction:
Let the moles of oxygen which react with C to form CO
2
be x
2C + O
2
→ 2CO
1−x (1−x)/2 1−x
C+O
2
→CO
2
x x x
We have, (1−x)/2+x=0.625
Hence, x=0.25
So, moles of carbon dioxide is equal to 0.25 and moles of carbon monoxide is equal to 0.75 .
So, mass of CO produced is 21 g and mass of CO
2
produced is 11 g.
