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.
What is the molarity of a solution containing 12.0 g of NaOH in 250.0 mL of solution? 16. Determine the molarity of these solutions: a) 4.67 moles of Li2SO3 dissolved to make 2.04 liters of solution. b) 0.629 moles of Al2O3 to make 1.500 liters of solution. c) 4.783 grams of Na2CO3 to make 10.00 liters of solution.
