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 0.0305 moles of nickel in a sample of nickel tetracarbonyl. how many moles of carbon are in the sample?
round your answer to 3 significant digits.
mol

Explanation:

Step1: Analyze the chemical formula

From the formula \(Ni(CO)_4\), we can see that for every 1 mole of \(Ni\), there are 4 moles of \(CO\). And since each \(CO\) has 1 mole of \(C\), for every 1 mole of \(Ni\), there are 4 moles of \(C\).

Step2: Calculate the moles of carbon

Given \(n_{Ni}=0.0305\) mol. Using the mole - ratio \(n_{C}=4\times n_{Ni}\).
Substitute \(n_{Ni}\) into the formula: \(n_{C}=4\times0.0305\) mol.

$$n_{C}=4\times0.0305 = 0.122$$

mol

Answer:

\(0.122\) mol
