Quizplus · Accepted Answer

To find the number of water molecules in one liter of water, we use the given density of water (1.00 x 10^3 grams/liter) and the mass of one mole of water (18.0 grams) to determine the number of moles in one liter. One liter of water weighs 1000 grams, so it contains 1000 grams / 18.0 grams/mole = 55.56 moles of water. Since one mole contains 6.02 x 10^23 molecules, 55.56 moles contain approximately 55.56 x 6.02 x 10^23 = 3.34 x 10^25 molecules.
