Web31 jan. 2024 · In 100 grams of water, there are 5.551 moles. To calculate this result: Calculate the molar mass of water, which is two hydrogen atoms' and one oxygen atom's molar masses combined: (2 × 1.008 g/mol) + 15.999 g/mol = 18.015 g/mol. Divide the mass of your sample by the molar mass: 100 g / 18.015 g/mol = 5.551 mol. WebAging is a major risk factor for many prevalent diseases.
