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.
Look up each element in your compound on the periodic table to find its molecular weight. To do this, find a periodic table and search for the symbol corresponding to your element. For example, you would search for sodium, or Na, in the periodic table to find that its molecular weight is 23.The molecular mass of chloride is 35. Add up the molecular weights to get the molar mass.n this case, you would divide the molar mass (58) by the total weight of salt that you have (46) to get 1.26 moles. This is the total number of moles of the compound, sodium chloride, that you have.
