Question

how many atoms of oxygen (o) are in the compound: *

p2o3

1 atom
2 atoms
3 atoms
4 atoms

Explanation:

Step1: Analyze the chemical formula

In the formula \(P_2O_3\), the subscript next to \(O\) (oxygen) is \(3\).

Step2: Determine the number of oxygen atoms

The subscript indicates the number of atoms of that element in the compound. So, there are \(3\) oxygen atoms.

Answer:

3 atoms
