Unfortunately, cold wet air can drive the spread of disease: The dew point on a cold day along the coast is 8° C. How many moles of water are in

a cubic meter (m) of this air if it's at 8° C? What is the mole fraction of water in this humid air at 8° C? What is the mole fraction of water if this humid air is raised to 25° C? How many moles of water are in a cubic meter (m) of this humid air if it's 25° C? \text { For water: } P^{s a t}=e^{23.6359-\frac{4169.5379}{7-28.6837}} P= PascalsT = Kelvin
