Answer 1

Answer:

moles of c = 12/12 = 1

moles of CA = 20/40 = 0.5

moles of O = 32/16 = 2

moles of K = 40/39 = 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.
