When a solution is diluted does it change the number of moles dissolved?
The number of moles of a solute will not change as a solution is diluted, however, the concentration of the solute will decrease. If you were to evaporate the water from the diluted solution, you would have the same number of moles of solute as when you started. You can test this by comparing the mass of the solute before producing the solution to the mass of the solute after the solution was diluted. The two masses should be the same.
A diluted protein solution (1 in 100) has an absorbance of 0.558 at 280nm when measured in a 1cm path-length cuvette. Calculate the concentration in mgmL of the undiluted protein solutions (extinctio?
One needs the extinction coefficient in order to answer this question. Otherwise it cannot be answered properly.
Is a 0.12M solution diluted?
This depends on the substance and the application.
What is the difference between a simple solution and dilute solution?
Any difference exist. A simple solution may be a diluted solution.
What is as stock solution?
A stock solution is a highly concentrated solution that is usually diluted in labs to get more precise moralities in experiments.
What is the actual absorbancy if 2mL of a culture is diluted by adding 4mL of water and the absorbancy reading of the diluted culture is 0.059?
If you multiple your absorbance by the dilution factor, this should give you the absorbance of the original culture.
WHY pH increases of strong acid when diluted?
When the acid is is diluted; its pH has a chance increase above seven and nake the sample;solution; Etc acidic.

What will be form in combining acetic acid and water what kind of solution is it?
It will be an aqueous acetic acid solution. normally water is added in order to decrease the concentration of an acid & gives the diluted form of it.
What happens if more solvent is added to a solution?
I presume from category that the question ask about the heat of dissolution. Assume the solvent and solution is at thermal equilibrium. Adding more solvent would yield change in interaction for non ideal solution and thus it could yield increase or decrease of temperature depend on the infinite heat of solution of the solute that we interested in. Adding more solvent would not yield temperature change for ideal solution.
How is concentration of hydronium ions affected when a solution of acid is diluted in water?
their is an increase in ion concentration
What is the component of a solution which is present in small amounts?
This is a diluted solution.

How do you describe a diluted solution?
solution that contains a small amount of solute
How many times a solution of pH equals 3 be diluted to get a solution of pH equals 6?
The solution must be diluted 1000 times to get from a pH of 3 to a pH of 6.
How would you prepare a liter of 10 percent ammonia solution from the official strong ammonia solution?
Diluted Ammonia solution can be prepared by diluted strong ammonia solution with the appropriate quantity of purified water.
Do you consider a solution with a small amount of solute to be dilute or concentrated?
This solution is diluted.
