A `0.2 mL` sample of a solution containing `1.0xx10^(-7)` curie of `._(1)^(3)H` is injected to the blood stream of an animal. After sufficient time for circulatory equilibrium to be established, `0.10 mL` of blood is found to have an activity of `20 dp m`. Calculate the volume of blood in animal, assuming no change in activity of sample during circulatory equilibrium.
