Convert moles to molecules - Conversion of Measurement Units

Web31 jan. 2024 · 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. This is the number of moles in 100 g of water. WebWhat is a mole and why are moles used? Answer: The mole is simply a very large number that is used by chemists as a unit of measurement. Explanation: The mole is simply a very large number, #6.022 xx 10^23#, that has a special property. If I have #6.022 xx 10^23# hydrogen atoms, I have a mass of 1 gram of hydrogen atoms .
