WebAtoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus. Protons and neutrons have approximately the same mass, about 1.67 × 10 -24 grams. Scientists arbitrarily define this amount of mass as one atomic mass unit (amu) or one Dalton, as Table 2.2 shows. WebThe molecular mass of a compound is the sum of atomic mass of all the atoms present in the given chemical compound. Mole concept is used to calculate the moles, mass, number of atoms and moles of a compound. The relation between these values can be shown as: Moles = mass molar mass 1 mole = N a atoms N a = 6.022 × 10 23
