Welcome back everyone. A non electrolyte solute shown below is placed in water. Choose the diagram that represents a solution formed from dissolving the solute. Now, looking at our given solute molecule, we have a blue sphere which represents one atom and then a red sphere bonded to it which represents our second atom making up our entire molecule. Let's begin by recalling that a non electrolyte solute or non electrolyte for short describes a molecule that does not will say it does not dissociate into ions, so it will remain intact in its molecular form. Now, looking at our given diagrams in representation, a we have nine moles that we can count of our unsociable solute molecules in their entirety making up our solution. This is definitely representative of a non electrolyte solution. Since we do not see any dissociated individual spheres representing ions moving on to diagram B, we can observe that a majority of our diagram contains our unassociated molecules of our non electrolyte solute. Whereas we have three individual spheres, two being blue and one being red, which make up dissolved ions within the solution. However, it's a very small portion. So we can say that our moles of solute are greater than our moles of dissociated ions. And so therefore, this is going to be a weak electrolyte aqueous solution. Next, in diagram C, the entirety of our solution depicted shows dissociated red spheres as ions and dissociated blue spheres as ions, meaning that our entire solution consists of dissociated molecules. So we have all dissociated, not molecules but dissociated ions. And so therefore, this choice C or diagram C represents a strong electrolyte aqueous solution. And lastly, we have diagram D which only consists of dissociated blue spheres as ions making up our entire solution ion. And so we only have an individual or we have individual ion particles only being just one type of our ion which is our blue sphere ion. So choice D would not even represent a strong electrolyte solution nor a weak elect sorry, nor a weak electrolyte solution, nor a non electrolyte solution. So choice D is going to be just a solution of one type of our ion particles. We can't really label it, but we're going to rule it out because it's definitely not going to be a non electrolyte solution since we don't even have our entire molecules of our solute represented in diagram D. So now looking at what we've labeled, we can confirm that the best choice is going to be choice a since again, it represents a solution which has unassociated entire molecules of our non electrolyte solute. So we would rule out choice B which is a weak electrolyte solution. And choice C which is a strong electrolyte solution. And that leaves us with diagram A or choice A as our final answer. I hope that this made sense and let us know if you have any questions.
