Question

how many atoms (total) are in a molecule of c₃h₈o? what atoms are present and how many of each atom?

Explanation:

Step1: Identify atoms and their counts

In \(C_3H_8O\), the subscript after each element symbol indicates the number of atoms. For \(C\) (carbon), sub - script is \(3\); for \(H\) (hydrogen), sub - script is \(8\); for \(O\) (oxygen), sub - script is \(1\) (when no sub - script is written, it is assumed to be \(1\)).

Step2: Calculate total number of atoms

Total number of atoms \(=3 + 8+1\)

Answer:

• Atoms present and their counts: \(3\) carbon (\(C\)) atoms, \(8\) hydrogen (\(H\)) atoms, and \(1\) oxygen (\(O\)) atom.
• Total number of atoms: \(12\)
