Question

Q. If one mole of carbon contains x atoms then the number of atoms in 12g of Mg are
(A) = x
(B) = 0.5x
(C )=2x
(D) = 1.5x​

Answer 1

We use the mole (mol) to represent the amount of substances in chemistry because the numbers of atoms and molecules in each substance is so large. The value given 6.022 x 1023 is called Avagadro's number for the scientist that found the number of atoms in 12 grams of carbon 12.
