In toxicology, the clearance is apharmacokineticmeasurement of the volume of plasma that is completely cleared off of a substance per unit time.The usual units are mL/min. The total body clearance will be equal to the renal clearance + hepatic clearance + lung clearance. ...
a 15 percent w/v sugar solution has a unit of weight in the numerator, but a unit of volume in the denominator. It is defined as a percentage, somewhat artificially; a 1 percent solution contains 1 gram per 100 milliliters (ml) of solution. This form of percent concentration is used ...
A mole of a chemical substance is composed of 6.02 × 1023 atoms or molecules of that substance. (The number of atoms in a mole is sometimes referred to as Avogadro’s number.) Molarity refers to the number of moles per liter of aqueous solution (mol/liter); in this book, molarity is...
Measured data so obtained is in the form of at least two time variations of the light responses of the medium characterized by different polarization states of detected light, respectively, a relation between the time variations being indicative of the concentration of the substance in blood.Boris ...
