Explanation:

The mass of the earth is 5.98*1027 grams. That's the scientific way to write a large number that has a lot of zeros. We can write the mass of the earth with all the zeros like this:

5,980,000,000,000,000,000,000,000,000 grams.

The bottom line is that there are about 1.33*10^50 atoms in the world.
