Solution Steps

Step 1: Identify the components of the chemical formula

The chemical formula for calcium bicarbonate is given as: \[ \mathrm{Ca}\left(\mathrm{HCO}_{3}\right)_{2} \]

Step 2: Determine the number of bicarbonate ions

The subscript "2" outside the parentheses indicates that there are 2 bicarbonate ions (\(\mathrm{HCO}_{3}\)) in each formula unit of calcium bicarbonate.

Step 3: Count the carbon atoms in each bicarbonate ion

Each bicarbonate ion (\(\mathrm{HCO}_{3}\)) contains 1 carbon atom.

Step 4: Calculate the total number of carbon atoms

Since there are 2 bicarbonate ions and each contains 1 carbon atom, the total number of carbon atoms is: \[ 2 \times 1 = 2 \]

Final Answer

\(\boxed{2}\)
