Chapter 3: Composition of Substances and Solutions Molecular and Formula Mass  The molecular mass is the mass in atomic mass units (amu) of an individual molecule. o To calculate the molecular mass, multiply the atomic mass for each element in a molecule by the number of atoms of that element and then total the masses. Example: Molecular Mass of HOH= 2(atomic mass of H) +atomic mass of O =2(1.008)+16.00amu=18.02 amu  Molecular weight is an average molecular mass, determined by the periodic table atomic masses, which are average atomic masses. Formula Mass  Formula Mass- a sum of the atomic weights of the atoms in the empirical formula of the compound.  To calculate the formula mass, it is the same process of calculating the molecular mass. The Mole and Molar Mass  The mole is defined as the amount of substance that contains as many elementary entities as there are atoms in exactly 12g of carbon-12.  The mole determined Avogadro’s number. o Avogadro’s number is: 1mole=6.022∗10 23  Molar Mass  The molar mass of a substance is the mass in grams of one mole of the substance. o The mass of a mole of cabon-12 by definition is exactly 12g.  Mass of 1 carbon-12 atom= 12 amu  Mass of 1 mole of carbon-12= 12g Grams to moles Molecular mass Molecular mass
