To find the number of nucleons present in an atom find the molar mass{Nucleon number} of the atom.

Mass of one atom#rArr 3.32xx10^-23#g

Molar mass of atom#=#mass of one atom#xx#Avogadro number #=3.32xx10^-23#gm#xx#6.022#xx10^23#

#=19.9931~~#20#(g)/("mole")#

No. of nucleons present in 1 atom :20

Therefore No. of nucleons present in 2 atom: 40
