Question - 1) A volume of liquid was measured to be 5.068ml. If the percent error was determined to be +13.60%, what was the true volume of the liquid?

2) A gas system has an intial pressure temp of 25.5 deg C with the intial pressure unknown. When pressuer changes to 12.2 kPa at constant volume, the temp is found to be -13.6 deg C. What was the initial pressure in units of kPa?

3) The pressure of the gas above the unknown liquid held at a temp of 2.65 deg C was measured to be 91.4 kPa. When the liquids temp was raised to 45.2 deg C the recorded total pressure of gas above the liquid was measured to be 118.6 kPa. What was the vapor pressure of liquid (in kPa) at 45.2 deg C?
