A 75 mL sample of fluorine gas has a pressure of 750. mm Hg and a temperature of 47.5°C. Calculate the pressure (atm) of the gas if the volume is changed to 35 mL and the temperature is raised to 225 °C.

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.
