Step-by-step explanation:

To determine the number of moles in 108 grams of water (H2O), we can use the molar mass of water as a conversion factor. The molar mass of water is 18.02 grams per mole. So, to find the number of moles, divide the given mass by the molar mass:

Number of moles = Mass of water / Molar mass of water

Number of moles = 108 g / 18.02 g/mol

Number of moles = 6 moles.
