Convert mass to the number of molecules?

The mistake lies in [ * (100 g / 1mg )] : it should be diveded 100.

Going over the steps again:

– C→12.011 g/mol

– H→1.0079 g/mol

-O→15,994 g/mol

so, as you said: C13H18O2 → 206.284 g/mol.

200 mg = 200 * 10^[-3] g.

# of mol = (200*10^[-3]) / (206.284) [g]*[mol / g] = 0.9695371 * 10^[-3] mol.

Avogadro=6.022*10^[23].

#molecules = 0.9695371 * 10^[-3] * 6.022*10^[23] = 5.83 * 10^[20] molecules.

hope this helps…
