Awelder using a tank of volume 7.60×10−2 m3 fills it with oxygen (with a molar mass of 32.0 g/mol ) at a gauge pressure of 3.05×105 pa and temperature of 35.4 ∘c. the tank has a small leak, and in time some of the oxygen leaks out. on a day when the temperature is 20.8 ∘c, the gauge pressure of the oxygen in the tank is 1.95×105 pa. find the initial mass of oxygen. (in kg)

It is reasonable to assume that the bulk modulus of blood is about the same as that of water (2.2 gpa). as one goes deeper and deeper in the ocean, the pressure increases by 10000 pa for every meter below the surface. if a diver goes down 80.0 m in the ocean, by how much does each cubic centimeter of her blood change in volume? give the answer in cubic centimeters (actually one cubic centimeter equals one milliliter).
