Well "Avogadro's number" of water molecules has a mass of 18.01*g.......

Explanation:

And "Avogadro's number"-=6.022xx10^23*mol^-1

And thus the mass of 20xx10^6*"water molecules"

-=(20xx10^6*"water molecules"xx18.01*g*mol^-1)/(6.022xx10^23*"water molecules"*mol^-1)

=6xx10^-16*g.........or 1/8xx1/5xx1/32*"sweet F....... A..."

And no balance could measure this........
