Question

The measured osmotic pressure of seawater is 24.8 bar at 273 K.

Part A

What is the activity of water in seawater at 273 K? Take the partial molar volume of water in seawater to be 18.0 mLmol1.

Express your answer using three significant figures.

Part B

The vapor pressure of pure water at 273 K is 4.6 torr. What is the vapor pressure of water in seawater at this temperature?

Express your answer to two significant figures and include the appropriate units.

Part C

What temperature would you expect to find for seawater in equilibrium with the polar ice caps? The melting point of pure water at 1 bar pressure is 0C and fH may be taken as 6.0 kJmol1 independent of temperature.

Express your answer using three significant figures.
