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

Explanation:

And $Avogadro's number \equiv 6.022 \times 10^{23} \cdot m o l^{- 1}$ $"Avogadro's number"-=6.022xx10^23*mol^-1$

And thus the mass of $20 \times 10^{6} \cdot water molecules$ $20xx10^6*"water molecules"$

$\equiv \frac{20 \times 10^{6} \cdot water molecules \times 18.01 \cdot g \cdot m o l^{- 1}}{6.022 \times 10^{23} \cdot water molecules \cdot m o l^{- 1}}$ $-=(20xx10^6*"water molecules"xx18.01*g*mol^-1)/(6.022xx10^23*"water molecules"*mol^-1)$

$= 6 \times 10^{- 16} \cdot g$ $=6xx10^-16*g$ .........or $\frac{1}{8} \times \frac{1}{5} \times \frac{1}{32} \cdot sweet F....... A...$ $1/8xx1/5xx1/32*"sweet F....... A..."$

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