A student is in a hurry and all his trials are hot pink.  Is his calculated molarity too high or too low?  Explain

How do I find the volume of the NaOH and the molarity of acetic acid

It takes 14.7 mL of 7.46 x 10-1 M sodium hydroxide to reach equivalence with 8.8 mL of an unknown molarity acid.  Determine the molarity of the acid.  Record your answer to three decimal places.(

Lead is a possible contaminant in public water systems. There are many reasons we should be concerned about this, but this may be especially concerning if the water is used for drinking. Removing all lead is not feasible, so many local governments must set an “acceptable” concentration for contaminants. The “acceptable” concentration of lead in public water for some states is 7.2 x 10^-7 M.   If 10.00 mL of 1.00 M lead is poured down the sink, how many liters of water are required to make sure the concentration of lead is 7.1 x 10^-7 M, which is just below the acceptable level?

1 of 4 Watch the video that shows using the dilution method to make a solution of known concentration. 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. This means we can use a simple ennation (Emation 4 2) to calculate the volume or concentration of either the stock solution or the more dilute solution Fauation 4 2 is stv hulu W

Use the solubility chart below to answer the following question: A beaker filled with 100 g of water is saturated with NH4Cl at 70 °C. If this solution is cooled to 50 °C, what mass of NH4Cl will precipitate out of solution?

Use the References to access important values if needed for this question. A student weighs out a 6.27 g sample of AlBr3, transfers it to a 100. mL volumetric flask, adds enough water to dissolve it and then adds water to the 100. mL tick mark. What is the molarity of aluminum bromide in the resulting solution? Molarity M %3D
