A flight attendant shares 3 things most people don't know about training school. It's been said getting invited to the Delta flight-attendant training center is more difficult than getting into Harvard University.
Molar Solutions A 1 molar solution is a solution in which 1 mole of a compound is dissolved in a total volume of 1 litre. For example: The molecular weight of sodium chloride (NaCl) is 58.44, so one gram molecular weight (= 1 mole) is 58.44g. If you dissolve 58.44g of NaCl in a final volume of 1 litre, you have made a 1M NaCl solution. To make a 0.1M NaCl solution, you could weigh 5.844g of NaCl and dissolve it in 1 litre of water; OR 0.5844g of NaCl in 100mL of water (see animation below); OR make a 1:10 dilution of a 1M sample.
Multiply the element's atomic mass by the molar mass constant by the number of atoms of that element in the compound. Here's how you do it: 1  For hydrogen chloride, HCl, the molar mass of each element is 1.007 grams per mole for hydrogen and 35.453 grams per mole for chlorine.his converts atomic units to grams per mole, making the molar mass of hydrogen 1.007 grams per mole, of carbon 12.0107 grams per mole, of oxygen 15.9994 grams per mole and of chlorine 35.453 grams per mole. 3. Find the molar mass of a divalent molecule. Some elements are only found in molecules of 2 or more.
