For the following questions, assur vapor pressure of water (a cylinder is submerged in water etc.). an experimental set up similar to what used to determine the we A) At low temperature (0 °C), the volume (corrected) in the cylinder was 3.6 mL. The gas pressure inside the cylinder was 768 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 (show method). B) At a higher temperature, the partial pressure of air inside the cylinder Hg. Assuming that the total pressure was 768 mm Hg, determine the partial pressure of water vapor in the cylinder. was determined to be 556 mm C) Relative to the volume in part A (3.6 mL), would the volume of gas inside the cylinder for part B be higher or would it be lower?
