Experiment 2: A graph of 1 /pressure in \( a^{-1}{ }^{-1} \) on the \( y \)-axis versus the volume of air in the flask in milliliters ( \( \mathrm{mL} \) ) on the \( x \)-axis shows a linear relationship. The equation of the linear trendline (best-fit line) fitted to the data is \( y=0.00550 x-0.000645 \), Use the equation of the best-fit line to calculate the pressure of the air in a flask when \( 120 \mathrm{~mL} \) of water is added to a flask that has a maximum volume of \( 250 \mathrm{~mL} \). \[ P= \]
