Convert grams C2H5Cl to moles - Conversion of Measurement Units

WebA mole is any item that contains the same number of that item as the number of atoms in exactly 12 g of 12 C. This means that in 12 g of C there are exactly 6.022 x 10 23 atoms of carbon. Each atom of C has a mass of 12 amu's, which means that: Now we are getting somewhere. Ethanol is CH 3 CH 2 OH. Its total mass is 46 u: Webm = 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.
