Explanation / Answer

1. Body mass index is a measure of obesity and it is calculated by taking your BODY MASS.divided by the square of your HEIGHT.

2. The osmolarity of 1M CaCl2 is ________3_______OsM whereas the osmolarity of 1M KCl is ___2________OsM

3. for each of the following sugar classify them as (M) monosaccharide, (D) Disaccharide, (O) oligosacchairde, (P) polysacchairde                                 

                             Cellulose POLY SACCHARIDE
                             fructose   DISACCHARIDE
                            glucose    MONOSACCHARIDE
                           galactose   DISACCHARIDE
                           Lactose    DISACCHARIDE
                           maltose   disaccharide
                            Sucrose disaccharide

                            glycogen polysaccharide

CaCl2 bcos 1 molecule of cacl2 dissociate into 3 ions 1ca and 2 cl ions.

osmotic pressure is a function of no of particles..   
CaCl2.... osmolarity=g x c

CaCl2 dissociates into 3 molecules in solution, so 1 M of CaCl2

=3 x 1 = 3 osm/l

as for KCl , it yeilds 2 molecules

so 1 M kcl = 2 x 1 = 2 osm/l

osmotic pressure is directly proportional to number of particles
