document.write( "Question 1161934: A biologist wants to determine the blood volume of a small animal. It has a solution with 4% of a certain inert chemical compound. Inject 2.5 cm^3 of that solution into the animal's blood and wait until it has mixed well with the animal's blood. Take a small sample and the analysis indicates 0.2% of the inert product. What is the volume in cm^3 of the blood that the animal has? \n" ); document.write( "
