Final answer:
The expression (0.2-0.4 Osm) is not equivalent to (200-400 mOsm) because osmolarity is a measure of the concentration of solute particles in a solution.
Step-by-step explanation:
The expression (0.2-0.4 Osm) is not equivalent to (200-400 mOsm) because osmolarity is a measure of the concentration of solute particles in a solution.
Osmolarity is usually expressed in units of osmoles per liter (osmol/L) or milliosmoles per liter (mOsm/L), while the calculation (0.2-0.4 Osm) is mathematically incorrect.
Therefore, the statement is false and the correct answer is b) False.
