Solutions are formed when solutes dissolve in solvents. If the number of moles of solute and the volume of solvent used is known, the concentration of the solution can be calculated.

Making up chemical solutions? Take the pain out of molarity and concentration calculations with this handy tool.

To do this, start your solution with the salt concentration in which the egg first floated and make a new dilution series, as you did before. Now in which cup does the egg first float?
