Question

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

Answer 1

$\huge{\textcolor{red}{\star{\mathcal{Answer :≈\star}}}}$

$\implies$ No. moles of carbon atoms = 12/12 = 1


A C-12 atom contains 12 nucleons (6 protons and 6 neutrons),

$\implies$Formula ⤵⤵⤵

$\implies$A = Z + N

$\implies$ A— Atomic mass

$\implies$ Z —Atomic number

$\implies$N = no. of Neutrons


There Fore, the total number of nucleons present is = 12 × 6.022×1023

$\implies$= 7.226×1024.

Answer 2

Hi


Here is the answer

No. Of moles in carbon atoms=1 mole


We know, no of atoms = avagadro no. ×number of moles =1×1.6022×10^23=6.022×10^23


In one atom there are 6 proton and 6 neurons

I. E 12 nucleon


So no. Of nucleon =6.022 ×10 ^23 ×12=7.2264§
×10^24

Thanks

Hope it helps and mark me brainliest
