What will be the mass of one `.^(12)C` atom in `g`?

Text Solution

Verified by Experts

`1 mol` of `.^(12)C` atoms `=6.022xx10^(23)` atoms`=12 g`
Thus, `6.022xx10^(23)` atoms of `.^(12)C` have mass`=12 g`
Therefore, `1 "atoms"` of `.^(12)C` will have mass
`=12/(6.022xx10^(23))g=1.9927xx10^(-23) g`
