Explanation:

Step1: Analyze the formula

In the formula \(3NaHCO_3\), the subscript of \(O\) in \(NaHCO_3\) is \(3\).

Step2: Consider the coefficient

The coefficient of \(NaHCO_3\) is \(3\). To find the total number of \(O\) atoms, multiply the subscript of \(O\) by the coefficient. So the number of \(O\) atoms is \(3\times3 = 9\).

Answer:

C. 9
