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
