14.82%, rounded to two decimal places.

Explanation:

Chemical formula of Calcium bicarbonate, also called calcium hydrogen carbonate is "Ca(HCO"_3)_2
Using Average Atomic weights we see that
Molar mass is $= 40.078 + 2 \times 1.0079 + 2 \times 12.011 + 6 \times 15.999$
$= 162.1098 {\text{g mol}}^{-} 1$
$\therefore$ Percentage of carbon $= \frac{24.022}{162.1098} \times 100$
=14.82%#, rounded to two decimal places.
