7.16: Concentrations: Molarity Equation and Calculations

WebMolar weight (MW) = mass of one mole of a substance in grams (g/mol). The MW of a molecule is a sum of relative atomic weights A r (expressed in grams per mole) of all elements building the molecule. The values of A r are found in the Periodic table, e.g. A r of H = 1, N = 14, O = 16 → molar weight of HNO 3 = 1x1 + 1x14 + 3x16 = 63 g/mol. WebWe do not know the concentration in molarity.
