Write the equality and conversion factors for the relationship between miles and hours for a car traveling at 55 mi/h

Using Raoult’s Law, we can calculate for the vapor pressure using the formula:

P = x * P (pure)

Where x is the mole fraction of water, P (pure) = pressure of pure water, P = pressure when in solution

calculating for mole fraction of water:

x = (0.42kg / 18kg/kmol) / ((0.42kg / 18kg/kmol) + (0.075kg / 192.12kg/kmol))

x = 0.9835

Therefore:

P = 0.9835 * P (71.93 mmHg)

P = 70.75 mmHg
