A red blood cell is placed into each of the following solutions. Indicate whether crenation, hemolysis, or neither will occur. Solution A: 3.62 % (m/v) NaCl
Solution B: 1.18 % (m/v) glucose
Solution C: distilled H2O
Solution D: 6.42 % (m/v) glucose
Solution E: 5.0% (m/v) glucose and 0.9% (m/v) NaCl

The size (radius) of an oxygen molecule is about 2.0 ×10−10m. make a rough estimate of the pressure at which the finite volume of the molecules should cause noticeable deviations from ideal-gas behavior at ordinary temperatures (t= 300k ). assume that deviatons would be noticeable when volume of the gas per molecule equals the volume of the molecule itself.
