A sample of water in the vapor phase (no liquid present) in a flask of constant volume exerts a pressure of 438 mm hg at 95 °c. the flask is slowly cooled. a). assuming no condensation, use the ideal gas law to calculate the pressure of the vapor at 93 °c; at 71 °c.

b. will condensation occur at 93 °c; 71 °c? explain.

c. on the basis of your answers in

a. and b), predict the pressure exerted by the water vapor in the flask at 93 °c; at 71 °c.
