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%

because natural gas is colorless, odorless, and tasteless, distributors add mercaptan (a chemical that smells like sulfur) to give natural gas a distinct unpleasant odor (it smells like rotten eggs). they locate the types of rock that are likely to contain natural gas deposits.
