Cobalt-60 can be used as a medical radiation source. Cobalt-60 exhibits first order decay and has a half-life of 5.26 years. If it must be replaced in a radiotherapy unit when its radioactivity decreases to 75% of its original value, how long can a 1.00 g sample be employed? (Treat the mass of cobalt as you would molarity in an integrated rate law).
Many drugs are high-molecular-weight amines that are weak bases. Such amines are not soluble in water, which limits the ways they can be administered and means that they are not soluble in body fluids such as blood plasma and cerebrospinal fluid
