A student constructs a simple constant volume gas thermometer and calibrates it using the boiling point of water, 100°C, and the freezing point of a specific brine solution, -17°C. The pressures measured at the calibration points are 1.366 atm and 0.9267 atm, respectively.   **when explaining please use math symbols & equations rather than typing it out, gets confusing if something is in a fraction or whatnot. Thank you!

Evaluation of the Gas Law Constant   PROCEDURE 1) Get a piece of magnesium ribbon that has a mass between 0.0300-0.0400g. Clean thoroughly with emery cloth. After cleaning, do not handle the ribbon with your hands. 2) Obtain an eudiometer and rinse thoroughly with water ifit is not clean and dry. 3) Fill one liter beaker half full of tap water. 4) Empty the eudiometer oiny water remaining. Fill it to the 25.0mL mark with the 3.0 M hydrochloric acid. Caution: Hydrochloric acid is very caustic. Wear goggles at all times. Fill the eudiometer to the top with distilled water. Make a "v" out of the piece of magnesium ribbon and wedge it into the eudiometer in the distilled water. 5) Put your finger over the top of the eudiometer and quickly invert it and put the top into the beaker of water. Remove your finger. 6) After the ribbon has completely reacted, record the volume of the gas in the eudiometer. 7) Repeat as time permits.   DATA Barometric Pressure 768 torr Vapor Pressure…
