Answer:
38 moles of oxygen
Step-by-step explanation:
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 9.6 moles of nickel in a sample of nickel tetracarbonyl. How many moles of oxygen are in the sample?
Step 1: Given data
Chemical formula of nickel tetracarbonyl: Ni(CO)₄
Moles of nickel: 9.6 moles
Step 2: Establish the molar ratio of nickel to oxygen
According to the chemical formula, the molar ratio of nickel to oxygen is 1:4.
Step 3: Calculate the moles of oxygen that accompany 9.6 moles of nickel.
We will use the previously established molar ratio.
9.6 mol Ni × (4 mol O/1 mol Ni) = 38 mol O
