Determine how to prepare 2.00 L of 0.157 M HCl solution from a 12.3 M stock HCl solution.

Answer 1

Use the dilution formula of
M1 x mL1 = M2 x mL2
12.3 x mL1 = 2,000 mL x 0.157
Solve for mL1 = the volume of 12.3 M HCl stock to add to a 2.00 L volumetric flask. Add distilled water to the flask and make to the mark, stopper, mix thoroughly, label.
