This means that one mole of water weighs 18.02 grams. To find how many moles of water are in 8.6 grams, you divide the mass (8.6 g) by the molar mass (18.02 g\/mol). The result, <strong>0.477 moles<\/strong>, tells you how many moles of water are in the given mass. Moles are a fundamental concept in chemistry, representing a specific quantity of molecules, atoms, or particles. By converting grams to moles, you can perform further chemical calculations, like determining the number of molecules in a given sample or how much of a substance is needed for a chemical reaction.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img decoding=\"async\" src=\"https:\/\/learnexams.com\/blog\/wp-content\/uploads\/2025\/07\/learnexams-banner6-196.jpeg\" alt=\"\" class=\"wp-image-251948\"\/><\/figure>\n","protected":false},"excerpt":{"rendered":"<p>Water (H2O) has a molar mass of 18.02 g\/mol.
