How many moles are in one liter of water?

In total, there are 55.55 moles of water in 1 L of water. Here is how you calculate it: * 1 mol of water (H20) = 18 g * Mass of 1 L of water = 1000 g How many times can you fit 18 g packets (moles) into 1000 g? 1000g/18g = 55. read more

For example, a mole of sodium chloride dissolved in 1 liter of solution has a molarity of 1 mole per liter. Pure water is not a solution, so molarity is found by dividing grams per liter by grams per mole, giving an answer expressed in moles per liter. read more

Therefore, one liter of water contains 1000 grams * (1 mole / 18 grams) = 55.56 moles of water. Because there are 6.022 * 10^23 molecules in a mole, the number of molecules of water in a liter is (6.022 * 10^23) * 55.56 = approximately 3.345 * 10^25 molecules of water. read more
