How many electrons protons, and neutrons...

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

Text Solution

Verified by Experts

The correct Answer is:
`36xx10^(23), 36xx10^(23), 48xx10^(23)`

Each atom of `._(6)C^(14)` contains 6 protons, 8 neutrons and 6 electrons and there are `6xx10^(23)` such atoms in 14 gm. of Carbon 14.
