Question

If there are a `10*mol` quantity of CARBON ATOMS in a sample of propane, what is the molar quantity of this hydrocarbon?

Answer 1

There are clearly `10/3` `mol` propane. Why?

Explanation:

Each formula unit of propane contains 3 carbon atoms, and 8 hydrogen atoms. Thus if there are `10.0` `mol` carbon atoms in the propane sample, there are:

`10/3` `mol` `C_3H_8` and `80/3` `mol` `H` atoms.
