14.82%14.82%, rounded to two decimal places.

Explanation:

Chemical formula of Calcium bicarbonate, also called calcium hydrogen carbonate is "Ca(HCO"_3)_2Ca(HCO3)2
Using Average Atomic weights we see that
Molar mass is =40.078+2xx1.0079+2xx12.011+6xx15.999=40.078+2×1.0079+2×12.011+6×15.999
=162.1098 "g mol"^-1=162.1098g mol−1
:. Percentage of carbon =24.022/162.1098xx100
=14.82%, rounded to two decimal places.
