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
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.
#molecules = 0.9695371 * 10^[-3] * 6.022*10^ = 5.83 * 10^ molecules.
hope this helps…
