5) A student titrated a 25.00 mL sample of HCI with an unknown concentration with 0.150 M NaOH. Phenolphthalein was used as an indicator. The initial
volume of NaOH solution before the titration was 1.07 mL.
A. Record the final volume of NaOH according to the picture of the buret.
B. Find the total volume of NaOH solution used to reach the end point.
C. Calculate the molarity of the HCl solution.

In november 1987, a massive iceberg broke loose from the antartic ice mass and floated free in the ocean. the chunk of ice was estimated to be 98 mi long, 25 mi wide, and 750 ft thick. a typical backyard swimming pool contains about 24,000 gallons of water. how many of these pools could you fill from the water in this iceberg? (assume the iceberg is a rectangular solid of the above dimensions and consists of water only). express answer in scientific notation.
