Dominican University Student Project ONS Challenge Procedure
 * 1) Add 1.001g of succinic acid to a 50mL beaker.
 * 2) Measure 12 mL of Ethanol with a graduated cylinder and add it to the 50mL beaker containing the succinic acid
 * 3) Swirl the reactants to mix, continue to stir the reactants using a glass stir rod. (solid will not totally dissolve)
 * 4) Record the masses of four centrifuge tubes to the hundredth of a gram and label them 1, 2, 3, and 4
 * 5) Using a 1mL dropper, distribute the saturated solution equally into the four centrifuge tubes.
 * 6) Record the volume of saturated solution in each of the centrifuge tubes to the tenth of a mL.
 * 7) Record the masses of the four centrifuge tube with the saturated solutions inside to the hundredth of a gram.
 * 8) Centrifuge each tube for 3 minutes and record any observations
 * 9) Gather and weigh four identical vials without the lids to the nearest hundredth of a gram. Label them 1, 2, 3, and 4
 * 10) Transfer the centrifuged saturated solution one to the vial labeled one.
 * 11) Continue to transfer the saturated solutions to each of the other vials.
 * 12) Record the masses of each of the vials containing the saturated solutions.
 * 13) Prepare four 50mL hot water baths and place them on a hot plate.
 * 14) Inside of each 50mL beaker place a vial that contains the saturated solution.
 * 15) Continue to heat the vials until all of the solvent has evaporated. (be sure that the water from the hot water bath does not enter into the vials)
 * 16) Remove the vials from the hot water bath and allow them to cool to room temperature.
 * 17) Record the mass of the solute in the vials
 * 18) Allow the solute to continue to dry out over a 24 hour period
 * 19) Record the mass of each vial containing solute to the nearest hundredth of a gram.
