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.

Calculate the mole-to-pressure change ratio (a conversion factor)
