To begin your experiment, you will calibrate your apparatus by injecting air into a sealed reaction bottle while monitoring temperature and pressure. Suppose you inject 25.0 mL of air (initially at a temperature of 22.5oC and a pressure of 0.958 atm) into a bottle at the same temperature and pressure. After the injection, the pressure is observed to be 1.023 atm with no change in temperature.
A. How many moles of gas were in the syringe to cause this pressure change?
B. Calculate the mole-to-pressure change ratio (a conversion factor)
