Chapter 13, Problem 62E
A solution is prepared by adding 50.0 mL concentrated hydrochloric acid and 20.0 mL concentrated nitric acid to 300 mL water. More water is added until the final volume is 1.00 L. Calculate [H+], [OH−], and the pH for this solution. [Hint: Concentrated HCl is 38% HCl (by mass) and has a density of 1.19 g/mL; concentrated HNO3 is 70.% HNO3 (by mass) and has a density of 1.42 g/mL.

Explain why the data points for the beaker lie roughly on a straight line. What kind of relationship is this? How do you know?
(see page 276 text) the design of the beaker is a uniform cylinder
the volume of liquid increases evenly with its height
resulting in a linear relationship.
What volume would you predict for 10.0 cm of water? Explain how you arrived at your answer. Use the data table and the
graph to assist you in answering the question.
4. Plot the volume of rain in milliliters versus its height in centimeters for the 250 mL Florence flask on the same graph. Draw a
best-fit curve through the points and label it "250 mL Florence flask."
