How many moles are in 125 g of water
WebHow to convert millimoles to moles? 1 Millimole (mmol) is equal to 0.001 mole (mol). To convert millimoles to moles, multiply the millimole value by 0.001 or divide by 1000. For example, to convert 100 mmol to mol, divide 100 by 1000, that makes 0.1 mol in 100 mmol. mmol to mole formula. mole = mmol * 0.001. mole = mmol / 1000.
