Question

Be sure to answer all parts. How many moles of O are needed to combine with 0.276 mole of C to form CO

Answer 1

0.138 moles of oxygen are needed to combine with 0.276 moles of carbon.

Step-by-step explanation:

Given data:

Moles of oxygen needed = ?

Moles of carbon present = 0.276 mol

Solution:

Chemical equation:

2C + O₂ → 2CO

Now we will compare the moles of carbon with oxygen.

C : O₂

2 : 1

0.276 : 1/2×0.276 = 0.138 mol

Thus, 0.138 moles of oxygen are needed to combine with 0.276 moles of carbon.
