Biology 48: Human Physiology Lecture 2 - Introduction to Physiology Osmolality (Osm) : • Number of :   Need to determine if the molecules will dissociate or distribute: a. Dissociate : Acids, bases, and salts (ions) One molecule : NaCl dissociates into : b. Distribute : Organic molecules-sugar, protein, fat Molecular structure : Molecules distributed by the greater : One Molecule remains: 1 m glucose = ____ Osm glucose Osm = molarity x # “wet pieces” (particles) molecule = mole glucose x solute particle 1 L H 2 O molecule =         Osm glucose  2 m glucose = ____ Osm glucose = mole glucose x solute particle 1 L H 2 O molecule =   Osm glucose 1 m NaCl = _____ Osm NaCl (Na + & Cl - ) = mole NaCl x solute particle 1 L H 2 O molecule = mole NaCl x NaCl solute particles 1 L H 2 O molecule =  Osm NaCl K 2 SO 4    2K +   +  SO 4 2- 1m K 2 SO 4 = ________ Osm 0.5 m K 2 SO 4 = _________ Osm 1
