What is the mass in grams of 100 atoms of carbon? (enter the number in scientific notation with units! )

Hello!

To find the mass in grams of 100 atoms of carbon, we need to use Avogadro's number, which is 6.02 x 10^23 grams, and divide that by the total number of atoms.

Next, we would need to find how much one mole of carbon weighs. In this case, it is exactly 12 grams.

1. Divide by Avogadro's number

100 / (6.02 x 10^23) ≈ 1.66 x 10^-22  

2. Multiply by one mole of carbon

(1.66 x 10^-22) x 12 ≈ 2.0 x 10^-21

Therefore, the mass of 100 atoms of carbon is equal to about 2.0 x 10^-21 grams.
