12 (5 points) How much 7.00N solution of $H_3AsO_4$ can I make with 57.0 mL of stock solution that is 84.0% assay and 1.14 specific gravity? 13 (5 points) If we have a 8.00N solution of HCl that has 0.03645g of HCl in the solution, how many microliters of solution do we have?

What is the molarity of a solution in which 6.4 grams of HCl is dissolved in enough water to make a 2400 mL solution?

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?

Hydrochloric acid is usually purchased in concentrated form with a $37.0 \%$ HCl concentration by mass and a density of $1.20 \mathrm{g} / \mathrm{mL} .$ How much of the concentrated stock solution in milliliters should you use to make $2.5 \mathrm{L}$ of $0.500 \mathrm{M} \mathrm{HCl} ?$
