Answer to Question #86138 in General Chemistry for mike

Question

In the laboratory you dilute 5.53 mL of a concentrated 3.00 M perchloric acid solution to a total volume of 100 mL. What is the concentration of the dilute solution?

________ M.

Answer 1

The concentrated solution of perchloric acid (5.53 mL) contains 3M × 0.0053 L = 0.0159 moles of perchloric acid.

Following the dilution, the molar concentration is 0.0159 mol / 0.1 L = 0.159 M.

Answer the concentration of the dilute solution is 0.159 M.
