Question

How many moles are in 63 grams of water (H2O)?

Answer 1

To find the number of moles in 108 grams of water, divide the given mass by the molar mass of water, which is 18.02 grams per mole. The number of moles is 6.

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.

Answer 2

Answer: 3.496 mol of H2O

Step-by-step explanation:

63 g H2O x __1 mol__ = 3.496 mol of H2O

18.016 g
