Suppose 50.0 dm³ of dry air at 25°C was slowly bubbled through a thermally insulated beaker containing 250 g of water initially at 25°C. The vapor pressure of water is approximately constant at 3.17 kPa throughout, and the heat capacity of the liquid is 75.5 J K-¹ mol-¹. Assume that the exit gas remains at 25°C and that water vapor is a perfect gas. The standard enthalpy of vaporization of water at 25°C is 44.0 kJ mol-¹. (a) Calculate the amount in moles of water in the 50.0 dm³ of air after it has bubbled through the liquid. (b) Calculate the finite temperature of the liquid.
