Find the total number of nucleons present in 12g of 12C atoms.

Expert Answer:

No of moles of carbon atoms = 12 g/12g/mole = 1 mole
 
We know that,
Number of atoms = number of moles x Avogadro number

= 1 x 6.022 x 1023 = 6.022 x 1023
 
In 1 atom of carbon there are 6 protons and 6 neutrons = 12 nucleons.
The number of nucleons = 6.022 x 1023 x 12
= 7.2264 x 1024
