Question

A number of beakers have different concentrations of a solution. Which statement best describes the most concentrated solution?

It has the largest volume.
It has the most solute for a given volume.
It has the greatest amount of solute.
It has the most volume for a given amount of solute.

Answer 1

B. It has the most solute for a given volume.

Step-by-step explanation:

I just did the test broskis ;)

Answer 2

It has the most solute for a given volume.

Step-by-step explanation:

Concentration of a solution with reference to volume can be expressed in terms of Molarity.

Molarity is the ratio number of moles of solute to the volume of solution measured in Liters i.e moles/L

`Molarity(M) = (Moles(solute))/(Volume(solution))----(1)`

Here moles of solute is the mass of the solute divided by its molecular weight.

`moles = (mass)/(mol.wt)`

Therefore, based on equation (1), if the volume of the solutions is all the beakers is constant, then the solution with the most solute (moles of solute) will be the most concentrated.
