Answer:

moles of C =

12

12

=1

moles of Ca =

40

20

=0.5

moles of O =

16

32

=2

moles of K =

39

40

=1.025

As 1 mole of every element contains Avogadro number of atoms. Hence, Equal number of moles of different elements will contain same number of atoms. Therefore, 12 g of Magnesium will have same number of atoms as in 20 g of Calcium.
