1 molecule contains 5 atoms
so 1 f.m.u. will contain 5 X 6.022 X 1023
= 3.011 X 1024 atoms
Water (H2O) has 3 atoms in each formula unit.
1 mole is KNO3 particles. Therefore, 5 moles of KNO3 have 5 x 6.022 x 1023 molecules of KNO3 . Now, 1 molecule of KNO3 has 5 atoms(1 of potassium, 1 of Nitrogen, 3 of oxygen). Therefore, total no. of atoms in 5 moles of KNO3 in KNO3 is 5 x 5 x 6.022 x 1023 =150.55 x 1023 atoms =1.50 x 1025 atoms.
The number of atoms in two formula units of potassium nitrate is 10.
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
There are a total of three oxygen atoms in the formula unit of calcium carbonate, CaCO3.
There's only 1 because the N does not have a subscript stating otherwise!
