In the solution was placed 100 molecules .Determine the degree of dissociation , if dissociated 95 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 in the solution.
In this case, we are given that 100 molecules were placed in the solution and 95 of them dissociated. Therefore, the number of dissociated molecules is 95, and the number of undissociated molecules is 100 — 95 = 5.
The degree of dissociation can be calculated as follows:
Degree of dissociation = (number of dissociated molecules / total number of molecules) x 100%
= (95 / 100) x 100%
= 95%
Therefore, the degree of dissociation in this solution is 95%. This means that 95% of the molecules in the solution dissociated into their constituent ions, while the remaining 5% remained undissociated.
