In the solution was placed 100 molecules .Determine the degree of dissociation , if dissociated 50 of molecules .
Ответ от учителя
The degree of dissociation is a measure of the extent to which a compound dissociates into its constituent ions in a solution. It is defined as the ratio of the number of dissociated molecules to the total number of molecules present in the solution.
In this case, we are given that 100 molecules were placed in the solution and 50 of them dissociated. Therefore, the total number of undissociated molecules remaining in the solution is 100 — 50 = 50.
The degree of dissociation can be calculated as follows:
Degree of dissociation = (Number of dissociated molecules / Total number of molecules) x 100%
= (50 / 100) x 100%
= 50%
Therefore, the degree of dissociation in this solution is 50%. This means that half of the molecules in the solution have dissociated into their constituent ions.
