Avagadro's number is the amount of molecules in a mole. This is 6.022x10^23 molecules. There will be 6.022x10^20 molecules in a millimole and 6.022x10^14 in a nanomole. Therefore, the difference between these is how many molecules there are in the difference. This gives you approx 6.021994x10^20 molecules. This is limited by the amount of significant figures for avagadros number that I know of.
This cannot be answered without the molecular weight. Multiply by molecular weight to get your answer

Since a mile contains 5280 feet, four miles contains 21,120 feet.
So, in a mole of anything, there are 6.022x10^23 molecules or atoms. There are 1000 millimoles in a mole, so 6.022x10^23/1000 is 6.022x10^20 atoms.
The molecule C9H8O4 contains 21 atoms.
1molecule of C2H6 contains 2 carbon atoms
Magnesium phosphide (Mg3P2) contains 2 atoms of phosphorus.
The molecular formula for tryptophan is C11H12N2O2, so it contains 12 atoms of hydrogen.
One mole of barium nitrate contains six moles of oxygen atoms. One formula contains 6 atoms.
Ammonia (NH3) contains a total of 4 atoms: 1 nitrogen atom and 3 hydrogen atoms.

One molecule of hydrogen peroxide (H2O2) contains two hydrogen atoms and two oxygen atoms, totaling four atoms.
6NaCl contains 6 atoms of sodium (Na) and 6 atoms of chlorine (Cl), totaling 12 atoms in total.
A chlorine molecule has the formula Cl2, so it contains two chlorine atoms.
Alcohol (C2H6O) contains 6 atoms of hydrogen.
