Question

5. Calculate the molarity of a solution made by diluting 0.050 L of 0.10 M HCl solution to a volume of 2.3 L. 6. If I have a 12.0 M stock solution of hydrochloric acid, and I need 500. mL of a 1.5 M hydrochloric acid solution: a. How much of the stock solution will I need? b. Approximately how much water will I have to add to the flask?

Step 1

050 L of 0.10 M HCl solution to a volume of 2.3 L. Step 2: Use the formula V1S1 = V2S2, where V1 = 0.050 L, S1 = 0.10 M, V2 = 2.3 L, and S2 is the molarity we need to find. Step 3: Calculate S2 = V1S1 / V2 = (0.050 L * 0.10 M) / 2.3 L = 0.00217 M. Step 4: Show more…
