1. Describe how you would make 500.0mL of 0.00400 M HCl from 0.0100M HC1? 2. Assume that you did an experiment and determine that a solution had a chloride ion concentration of 0.20 M. a. How many grams of chloride would be present in 50.0 mL of that solution? b. If the chloride in Part a. was the result of dissolving calcium chloride in the solution, how many grams of calcium chloride would be needed to make 50.0 mL of that solution? c. If all the chloride was due to calcium chloride, calculate the concentration of calcium chloride in mg/L of solution? Chem 162 page 46 I’m confused about part b. Am I supposed to do a mole to mole conversion?
