Question

Sum of number of protons, electrons and neutrons in 6 gm of 12 6 c is

Answer 1

Hi there,

Given

Carbon atom contains

6 protons

6 neutrons

6 electrons

Sample mass is 6 gm

Atomic mass of carbon is 12 gm

Avogadro's number = 6.02×10^23

◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇◇

So,

☆ Number of moles of the sample

is Sample mass ÷ atomic mass

= 6÷12=0.5 mol

☆ Number of atoms is

number of moles × avogadros nub

0.5×6.02×10^23 = 3.01×10^23 atom

☆ Sum of particals in one atom is 18 particals

☆ So total number of paricals are

18× 3.01×10^23
