Question

You discover a chemical reaction that produces 2 moles of valuable propane for every 8 moles of carbon supplied.

Essentially, this is an exchange rate of 2 moles of propane for every 8 moles of carbon.
If you have 1.7 moles of carbon, how many moles of propane can you produce using this reaction?

Answer 1

Here we have to get the amount of propane can be produced from the reaction of 1.7 moles of carbon (C).

1.7 moles of carbon will produce 0.425 moles of propane

In the reaction 8 moles of carbon is producing 2 moles of propane. Thus, mathematically,

8C → 2C₃H₈

Thus 8 moles of carbon produces 2 moles of propane

1.7 moles of carbon produces
`(2)/(8)`×1.7 = 0.425 moles

Thus 1.7 moles of carbon will produce 0.425 moles of propane.

Thus the amount of propane will be prepared from the reaction of 1.7 moles of carbon is determined.
