    First, we will convert the mass of the gallon to grams:

    a gallon of water has a mass of 3.79 * 1000 = 3790 grams of water

    number of moles can be calculated using the following rule:

    number of moles = mass / molar mass

    Therefore,

    number of moles = 3790 / 18.02 = 210.32 moles
