Question

a chemical engineer has determined by measurements that there are moles of carbon in a sample of nickel tetracarbonyl. how many moles of oxygen are in the sample? round your answer to significant digits.

Answer 1

A chemical engineer has determined by measurements that there are moles of carbon in a sample of nickel tetracarbonyl the no. moles of oxygen are in the sample are 7.0 moles.

• The chemical method of nickel tetracarbonyl is Ni(CO)4.
• We can see that there are four carbon atoms and four oxygen atoms which collectively shape four carbonyl (CO) groups.
• Therefore the mole ratio of C to O is 1:1.
• Let us use this as a conversion factor to locate moles of oxygen.
• We have 7.zero moles of carbon withinside the method.
• The moles of O may be calculated as,
• 7molC x (1molO)/(1molC) = 7molO.
• There are 7.zero moles of oxygen within side the method.
