Mass of atoms in grams

WebFinding molar mass starts with units of grams per mole (g/mol). When calculating molecular weight of a chemical compound, it tells us how many grams are in one mole of that substance. The formula weight is simply the weight in atomic mass units of all the atoms in a given formula. WebExample 1: Let's determine the mass of 1 dozen eggs. 1 egg mass = 60g and 1 dozen = 12. Therefore, 1 dozen of egg masses = 1 dozen of 60g = 12 of 60g = 12 x 60g = 720g Example 2: Show that 1 mole of 12C is 12g. Recall that, 1 amu = 1.6605 x 10^ (-27) kg and 1 mole = 6.02 x 10^23. 12C = 12 amu Therefore, 1 mole of 12C = 1 mole of 12 amu
