A test or experiment in which only one variable is changed at a time in order to verify the result is known as a controlled experiment.

There are a number of ways to express concentration of a solution. This includes molarity and molality. Molarity is expressed as the number of moles of solute per volume of the solution while molality is expressed as the number of moles solute per mass of solution.
Molarity = 5.25 mol / kg solution (1.266 kg / L) = 6.65 M
