Question

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 8.2 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.

Explanation:

Step1: Analyze the chemical formula

In $Ni(CO)_4$, the ratio of nickel (Ni) to carbon (C) is 1:4.

Step2: Calculate moles of carbon

If there are 8.2 moles of Ni, and the mole - ratio of Ni:C = 1:4, then the moles of C is $8.2\times4$.
$8.2\times4 = 32.8$

Answer:

32.8 mol
