Baseball reporters say that long fly balls that would have carried for home runs in July "die" in the cool air of October and are caught. The idea behind this observation is that a baseball carries better when the air is less dense. Dry air is a mixture of gases with an effective molar mass of 29.0g/mol

(a) Compute the density of dry air on a July day when the temperature is 308.15K and the pressure is 1.00atm

(b) suppose that the humidity on the July day is 100%; thus, tha air is saturated with water vapor.

Is the density of this hot, moist air less than, equal to, or greater than the density of the hot, dry air computed in part (a)? In other terms, does high humidity favor the home run?
