Given that the rates of breakdown of Benzocaine, a local anaesthetic are 16 x 10 second 15 10-8 sec at 30°C and 25°c respectively. Compute the shelf-life of an ampoule (Injection) of the
drug stored in the fridge at 5°C if the compendia provided a preparation of the drug shall contain
not less than 80% of benzocaine.

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).
