Compute the bulk -modulus of water from the following data: Initial volume = 100.0 litre, Pressure increase = 100.0 atm `(1 atm = 1.013 xx 10^5 Pa)`, Final volume = 100.5 litre. Compare the bulk modulus of water with that of air (at constant temperature). Explain in simple terms why the ratio is so large.

The Marina trench is located in the Pacific Ocean, and at one place it is nearly eleven km beneath the surface of water. The water pressure at the bottom of the trench is about 1.1 xx 10^8 Pa. A steel ball of initial volume 0.32 m3 is dropped into the ocean and falls to the bottom of the trench. What is the change in the volume of the ball when it reaches to the bottom?

Calculate the mass of CO_2 in 500 mL of soda water when packed unde 2.5 atm CO_2 pressure at 298K. Given that density of water is 1g mL^-1 and Henry's law constant for CO_2 in water is 1.67xx10^8 Pa at 298K.

100 mg of a protein is dissolved in just enough water to make 10.0 mL of solution. If this solution has an osmotic pressure of 13.3mm Hg at 25^@C , what is the molar mass of the protein? (R = 0.0821L atm mol^-1 K^-1 and 760mm Hg = 1atm)

What concentration of nitrogen should be present in a glass of water at room temperature at 25^@C , a total pressure of 1 atm and mole fraction on nitrogen in air of 0.78 [ K_H for nitrogen = 8.42xx10^(-7)M//mmHg ].
