A blood-volume determination was carried out on a patient by injection with 20.0 mL of blood that had been radioactively labeled with Cr-51 to an activity of 4.10 microCi/mL.
The van der Waals equation for n moles of a gas is (p+(((n^2) (a))/V^2 ))(v?nb)=nRT where p is pressure, V is Volume, and T is the temperature of gas. The constant R is the universal gas constant and a and b are positive constants that are charact..
What is the difference between a common name, IUPAC name, a name in an international journal, and a name in an American journal? I understand how to do IUPAC names, but then I am confused at the rest.
