Molarity Calculations - help2

Not all solutions are created equal. Some are more concentrated than others. Molarity is one means of expressing how concentrated a solution is with solute. Molarity is defined as the number of moles of solute per liter of solution. Its units are mole/liter, sometimes abbreviated with a capital M. Knowledge of the moles of solute and the liters of solution allows one to calculate molarity by division.

There are three very similar versions of questions in this Question Group. One of the versions is shown below.

Version 1:
Tap on the fields to accurately complete the statement regarding Solutions A and B.

The solute concentration in Solution _______ is greater than the solute concentration in Solution _______ by a factor of ____________.

The molarity of a solution is equal to the moles of solute per Liter of solution.

Molarity = # moles solute / Liters of solution

For two solutions with the same number of moles of solute, the one that has the greatest volume will have the smallest molarity. Put another way, it will be least concentrated with solute; its molarity will be less.

The molarity is inversely proportional to the volume of solution. So if a solution has two times the volume (but the same amount of solute), then it will have one-half the molarity. And if it has three times the volume, then it will have one-third the molarity. Put another way, a solution with one-half the volume (and the same amount of solute) will have two times the molarity.
