The solution was prepared by adding 150 g of sodium hydroxide to 150 g of water, giving a total weight of 300 g. Density of the solution is 1.53 g/mL What is the molarity of the solution? 2. Pause the Student Protocol video at 1 minute 39 seconds. Now use your molarity in the dilution equation to calculate the number of mL you will need to dilute to make 500 mL of a 0.10 M sodium hydroxide solution.
Imagine a small amount of each compound in the table below is dissolved in water. Pick the sketch that best shows what the solution would look like, at the atomic level. The large number of faint red and white molecules in the background of each sketch represent the water solvent. Also, the colors of the solute atoms may not mean the same element in each sketch. For example, solute oxygen atoms could be colored yellow in the first sketch but blue in the second. Chlorine atoms could be colored blue in the first sketch but yellow in the second. And so on.

Note that while the video shows the use of a beaker, in the lab we typically use a volumetric flask to make the diluted solution. The stock solution of KMNO, has a concentration of 2.6 x 10ª M. The pipette has a volume of 10.0 mL. What is the amount of KMNO. delivered to the solution, in moles? mol Submit When using the dilution method to prepare a solution of known concentration, remember that the total amount of solute is the same in both the measured volume of the more concentrated stock solution and in the dilute solution created.

Calculate the each initial CONCENTRATION for Pb(NO3)2 and KI before filling-out this chart. (Refer t Steps 1 and 2 of the procedure. Use the formula for Molarity to calculate the concentration of each salt after preparing the solution from the solid crystals dissolved in 100 mL of water. Do this for Lead (II) Nitrate and KI separately. Then use the dilution formula (starting with the initial concentration) for EACH beaker – each will have a the same total volume, but different volume of each solution added for each beaker. In short, FOR EACH BEAKER, multiple the concentration for Pb(NO3)2 with the concentration of KI.
