1. The pressure 55.0 meters under water is 641 kPa. What is this pressure in atm? What is this pressure in mmHg?

2. The organic compound di-n-butyl phthalate, C16H22O4(l), is sometimes used as a low-density (1.046 g·mL-1) manometer fluid. Compute the pressure (in torr) of a gas that supports a 455-mm column of di-n-butyl phthalate. The density of mercury is 13.53 g·mL-1.

3. An ideal gas is allowed to expand from 5.40 L to 29.7 L at constant temperature. By what factor does the volume increase? Also, If the intial pressure was 117 atm, what is the final pressure?

4. A sample of an ideal gas at 1.00 atm and a volume of 1.47 L was placed in a weighted balloon and dropped into the ocean. As the sample descended, the water pressure compressed the balloon and reduced its volume. When the pressure had increased to 75.0 atm, what was the volume of the sample? Assume that the temperature was held constant.

5. An ideal gas in a sealed container has an initial volume of 2.50 L. At constant pressure, it is cooled to 19.00 °C where its final volume is 1.75 L. What was the initial temperature?
