Question

1. calculate the osmotic concentration (osmolarity) of a 0.5 m glucose solution.

1.0 osm/l
0.5 osm/l
0.5 m
1.0 m
remember the units of osmolarity are osm/l

Explanation:

Step1: Identify solute type

Glucose is a non-electrolyte, so it does not dissociate in water. The number of particles (osmoles) per mole of glucose is 1.

Step2: Relate molarity to osmolarity

Osmolarity = Molarity × number of particles per mole.
Expression: $\text{Osmolarity} = 0.5\ \text{M} \times 1 = 0.5\ \text{Osm/L}$

Answer:

0.5 Osm/L
