    Divide the number of molecules you have by, 6.022 x 10^23. This will give you the moles of water, or the moles of anything, since there is always 6.022 x 10^23 molecules in 1 mole of substance.

    1.23x10^24 atoms/6.022x10^23 atom/mole = 2.04 mole H20

    The answer is 2.04x10^-6 moles of water.

    Explanation:

    Avogadro's number is defined as the number of particles found in an amount of substance per mole. It is the factor that relates the moles of a substance to the mass of that substance. We will use Avogadro's number to calculate the number of moles of water. as follows:

    Avogadro's number = 1 mol = 6.022 x 10^23 particles.

    we will use the conversion factor to calculate the number of moles of water:

    Moles of water = 1.23x10^18 particles x (1mol/6.022x10^23 particles) = 2.04x10^-6 moles
