Answer:
We have 12.54 moles of carbon are in the sample.
Explanation:
Step 1: Data given
Nickel tetracarbonyl = Ni(CO)4
Number of moles nickel = 3.134 moles
Step 2: Calculate moles carbon
For 1 mol Ni(CO)4 we have 1 mol Nickel, 4 moles carbon and 4 moles oxygen
If we have 3.134 moles nickel, this means we have 3.134 moles of Ni(CO)4
For 3.134 moles Ni(CO)4 we have 4*3.134 = 12.54 moles of Carbon
We have 12.54 moles of carbon are in the sample.
