Answer:
[tex]\boxed {\boxed {\sf B. \ 3}}[/tex]
Explanation:
First, identify the elements.
- H: Hydrogen
- Cl: Chlorine
- O: Oxygen
Next, identify any subscripts or coefficients. This would indicate there are multiple atoms of each element or group of elements.
There are none, so each element has 1 atom.
There are 3 elements with 1 atom each, so 3*1= 3
This chemical formula has 3 atoms and B is correct.
