1 molecule contains 5 atoms
so 1 f.m.u. will contain 5 X 6.022 X 1023
= 3.011 X 1024 atoms
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.
A formula unit of sodium acetate contain two oxygen atoms.
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
The formula unit of aluminum nitrate is Al(NO3)3. This shows that the formula unit contains 1 aluminum atom, 3 nitrogen atoms, and 9 oxygen atoms for a total of 13 atoms.
There's only 1 because the N does not have a subscript stating otherwise!

The formula unit of NaCl (sodium chloride) contain 2 atoms.
A formula unit of sodium acetate contain two oxygen atoms.
The compound sodium acetate is C2H3NaO2, so each formula unit has 2 oxygen atoms.
Here are 32 atoms in the formula unit.
1 molecule contains 5 atomsso 1 f.m.u. will contain 5 X 6.022 X 1023= 3.011 X 1024 atoms
For sodium chloride the term formula unit is more adequate than molecule; and the formula unit has two atoms.
Sodium chloride (NaCl) formula unit has one chlorine atom.
The formula unit indicate that this unit has 1 atom of strontium and two atoms of chlorine.
The formula unit indicate that this unit has 1 atom of strontium and two atoms of chlorine.
