At 22.0 degrees Celsius an "empty" 30-ml syringe had a volume of 5.0 ml. After a liquid is introduced and the temperature is raised to 32.0 degrees Celsius, the volume becomes 10.2 ml. The barometer pressure is 745.8 mmHg,
1. what was the pressure of the air inside the syringe when the syringe was "empty"?
2. What is the pressure of the air inside the syringe after the liquid has been introduced and the temperature raised to 32.0 degrees Celsius?
3. What is the vapor pressure of the liquid at the higher temperature?

A. At a low temperature (1 degree celsius), the volume in the cylinder was 3.8 mL. The gas pressure inside the cylinder was 764 mm Hg. Using the ideal gas equation, compute the number of moles of air. Be sure to convert the temperature and volume to appropriate units. B. At a higher temperature, the partial pressure of air inside the cylinder was determined to be 6.32 mm Hg. Assuming that the total pressure was 764 mm Hg, determine the...

A glass flask has a volume of 500 ml at a temperature of 20 degrees celsius. The flask contains 492 ml of mercury at an equilibrium temperature of 20 degrees celsius. The temperature is raised until the mercury reaches the 500 ml reference mark. The coefficients of volume expansion of mercury and glass are 18*10^-5 K^-1 and 2.0*10^-5 K^-1, respectively. The temperature at which this occurs, in degrees celsius is closest to:

A gas is placed in a 5.0-mL syringe. It exerts 149 mm Hg of pressure on the inside walls of the syringe. The syringe's plunger is pressed, reducing the volume of the syringe to 2.8 mL. The cap was not removed from the syringe, so none of the gas escapes. Assuming the temperature of the gas does not change, use Boyle's law (below) to determine the pressure of the compressed gas. P_1 V_1 = P_2V_2 mm Hg
