# How many atoms of each element are in the chemical formula Ca(OH)_2?

5

#### Explanation:

Ca is 1 since there is no subscript and O and H each have 2 because the subscript 2 is outside the parenthesis.

$i . e . \textcolor{red}{1} C a + \textcolor{red}{2} O + \textcolor{red}{2} H = 5 \text{ atoms}$
