Question

A sample of propane, C3H8, contains 17.0 moles of carbon atoms. How many total moles of atoms does the sample contain

Answer 1

The answer is "62.33 mol atoms".

Step-by-step explanation:

In the propane molecule, it includes 8 atoms of Hydrogen for every 3 atoms of Carbon or 8 mol Hydrogen atoms for each of the 3 mol Carbon atoms.

`\text{H atoms mole}= 17.0 \ \text{mols of C atoms} * \frac{8 \text{mol H atoms}}{3 \text{mol H atoms}} =45.33\ \text{mol H atoms}`

Total atoms = 17.0 mols of C atoms +45.33 mols of H atoms

=62.33 mol atoms
