WebA mole is simply 6.0223 x 10 23 molecules (this is “Avogadro’s number”) Eggs come in dozens (12), molecules come in moles (6 x 10 23) The mass of a mole of molecules is the formula weight in grams. This is sometimes called “molar mass” with symbol M. Sometimes it is referred to as molecular weight. Web31 jan. 2024 · m = 6 l × 998 kg/m³ = 0.006 m³ × 998 kg/m³= 5.988 kg. It's easier to work with grams, so convert the mass: 5.988 kg = 5988 g. As you already know how the grams to moles conversion work, find the number of moles: n = 5988 g / 18.015 g/mol = 332.4 mol. You can always use our grams to moles calculator to check the result!
