This is the chemical formula for nickel tetracarbonyl (a powerfully poisonous liquid used in nickel refining): Ni(CO)_4 A Chemical engineer has determined by measurements that there are 3.134 moles of nickel in a sample of nickel tetracarbonyl. How many moles of carbon are in the sample? Be sure your answer has the correct number of significant digits.

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.
