Wait what is the question
6.023 × individual carbon atoms are there in one mole of carbon.
Mass of a 1 atom= 12 amu
1 amu = 1.66 × gm
∴ 12 amu =1.99 × gm
∴Mass of a 1 atom=1.99 × gm
Mass of C in 1 mole = 12 gm
∴Total number of atoms of carbons in 1 mole = 12 ÷ 1.99 ×
∴Total number of atoms of carbons in 1 mole= 6.023 × atoms
6.023 × individual carbon atoms are there in one mole of carbon.
The number 6.023 × is known as Avogadro's number, which represents the number of individual atoms present in a one mole of substance with respect to atoms.
