Determining Molar Mass. We can use a measurement of any one of the following properties to determine the molar mass (molecular weight) of an unknown that is the solute in a solution: Boiling Point Elevation. …
WebWell, a molarity of 16 means that there are 16 moles of solute for every liter of solution. Based on density, if we have 1000 milliliters, we have 1420 grams of solution. To calculate the molality I need: 16 kilograms of solvent. Since we have 16 moles, and the molar mass of H N O X 3 is 63, we know that we have 1008 grams of solute, meaning ... WebJan 20, 2024 · What I know is that the formula for mole fraction is X = no.-of-moles-of-solute (no.-of-moles-of-solute) + (no.-of-moles-of-solvent) The solute is ammonia which is N H X 3 with a molar mass (MM) of 17 g m o l − 1, whereas the solvent is water or H X 2 O which has a molar mass of 18 g m o l − 1.
