Answer:
Id say A. Competition, hope this helps
Explanation:
Answer:
Albert Einstein is perhaps most famous for introducing the world to the equation E=mc2. In essence, he discovered that energy and mass are interchangeable, setting the stage for nuclear power—and atomic weapons. His part in the drama of nuclear war may have ended there if not for a simple refrigerator.

There are eight moles of oxygen atoms in 1 mole of 
.
<h3>What is the number of moles of oxygen atoms?</h3>
We know that a compound is composed of atoms. The atoms that make up the molecule are chemically combined. It is usual that the number of atoms in the compound would correspond with the chemical formula.
Now we have the compound . In one mole of the compound we have;
- 9 Moles of manganese atom
- 2 moles of chlorine atom
- 8 moles of oxygen atom
Thus, there are eight moles of oxygen atoms in 1 mole of .

The Half life is the time taken for a radioisotope or a radioactive substance to decay by half its original amount. The half life of carbon 14 is 5600 years.
Original mass is 100%
Remaining amount is 24%
Therefore; 0.24 = 1 × (1/2)^n
n = log 0.24/log 0.5
= 2.06
therefore, the age of the fossil is 5600×2.06
= 11529.8
≈ 11529 years
Counting gives an exact number and exact numbers have infinite sig figs.
