Answer:

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance occupies 22.4 Liters at STP and contains avogadro's number
6.023* 10^(23) of particles.

To calculate the moles, we use the equation:

$\text{Number of moles}=\frac{\text{Given molecules}}{\text {Avogadro's number}}$

$\text{Number of moles}=(1.23* 10^(18))/(6.023* 10^(23))=0.20* 10^(-5)moles$

Thus the moles of water are
