what is the osmolarity of a 1.0M solution of ethyl alcohol (C2H6O) in water?
Ethyl alcohol does not dissociate in water; therefore, a 1.0M solution is 1.0 osm/L
To find the osmolarity of a solution, you need to know the molar concentration of the solute (ethyl alcohol, C2H6O in this case). The osmolarity is calculated by multiplying the molar concentration by the number of particles formed when the solute dissolves in water.
In the case of ethyl alcohol (C2H6O), it does not dissociate into ions when it dissolves in water. It remains as individual molecules. Therefore, the number of particles formed is equal to the number of molecules of ethyl alcohol.
To find the osmolarity of a 1.0M solution of ethyl alcohol (C2H6O) in water, use the formula:
Osmolarity = Molarity × Number of Particles
In this case, the molar concentration (Molarity) is given as 1.0M. The number of particles is 1, as ethyl alcohol does not dissociate into ions.
Osmolarity = 1.0M × 1 = 1.0 osmol/L
Therefore, the osmolarity of a 1.0M solution of ethyl alcohol (C2H6O) in water is 1.0 osmol/L.
