How many electrons protons, and neutrons are there in `12 g` of `._(6) C^2` and in `14g` of `._(6) C^(14)` ?.

Explanation

Mass number (or atomic weight) of `._6 C^(12)` is `12`.
Therefore, the number of atoms in `12 g` of `._6 C^(12)` is
Avogadro number `=6 xx 10^(23)`
The number of electrons in `12 g _6 C^(12)` is
`6 xx 6 xx 10^(23) =36 xx 10^(23)`
The number of protons in `12g` of `._6 C^(12)` is `36 xx 10^(23)`
The number of neutrons in `12 g` of `._6 C^(12)` is
`(A-Z) xx 6 xx 10^(23) =(12-6) xx 6 xx 10 ^(23) =36 xx 10^(23)`
Similarly, number of electrons in `14 g` of `._6 C^(14)` is `36 xx 10^(23)`
Number of protons in `14 g` of `._6 C^(14)` is `36 xx 10^(23)`
Number of neutrons in `14 g` of `._6 C^(14) =(A -Z) xx 6 xx 10^(23)`
`=(14-6) xx 6 xx 10^(23)`
`=48 xx 10^(23)`.
