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.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
