Calculate the mass percentage of different elements present in caco3

Calcium=40.0%

Carbon= 12.0%

Oxygen= 48.0%

Explanation:

The mass per mole of calcium is approximately 100.09g/mole.

calcium has an atomic  mass of 40.08

carbon has an atomic mass of 12.01

Oxygen has a mass of 15.999

Thereof the 100.09g of calcium carbonate, calcium contributes 40.08g, carbon 12 and oxygen 16×3=48

Thus the percentages are calculated as follows.

Calcium (40.08/100.09)×100%=40.0%

Carbon (12.01/100.09)×100%=12.0%

oxygen (15.999/100.09)×100%=48.0%

they all get energy from eating other animals, dead animals to be more precise.

hienas tends to steal pray from other animals. crows and vultures tend to eat dead animals and leftovers.
