Question
You are asked to create a 0.35 M solution of calcium chloride (CaCl2) using a 250.0 mL volumetric flask.
- Calculate the mass of CaCl2 needed to make this stock (original) 0.35 M CaCl2 solution.
- You are asked to create 50.0 mL of 0.15 M CaCl2 from the stock solution you made in (A). Calculate the volume of stock solution you need to create your diluted solution.
- You have two solvents, difluoromethane (CH2F2) and ethanol (C2H5OH) available to dissolve your CaCl2. Which solvent would be more appropriate to use? Justify your response in 2 sentences or less.
- You react 30.0 mL of 0.35 M CaCl2 with excess solid lithium. The balanced reaction is shown below. What mass of solid calcium is made during this experiment?
CaCl2(aq) + 2 Li(s) → Ca(s) + 2 LiCl(aq)
