, CaCO3, contains one atom of calcium, one of carbon and three of oxygen. so there are 5 atoms in CaCO3

Mg(OH)2, There is  one magnesium, two oxygen, and two hydrogen atoms. so there are 5 atoms  Mg(OH)2

a molecule of acetic acid  contains two carbon atoms, four hydrogen atoms, and two oxygen atoms. so there are 8 atoms in acetic acid

There are 3 atoms in CaCl2

H2SO4 is a chemical compound made up of two hydrogen atom, one sulfer atom, and four oxygen atoms. So there are 7 atoms in H2SO4
