Problem- A) You are asked to prepare a 500.0 mL of a 0.750 M iron (III) chloride solution from a bottle that contains that solid. How many grams of iron (III) chloride would be needed to make this solution? Show work please.
B) = 0.016 L
C) A student obtains 25.0 mL of a 5.00M solution of HCl in a large beaker. The student then proceeds to add 400.0 mL of distilled water to the solution in the beaker. What is the concentration (molarity) of the diluted solution in the beaker?
