WebMay 22, 2015 · Problem: 70 grams of pure, hydrated M g S O X 4 is dissolved in 90 grams of H X 2 O. If the mole fraction of the solute is 0.039, find the molecular formula of the … WebOct 5, 2013 · For example, adding 50 mL of ethanol to 50 mL of water will result in a total volume that is less than 100 mL. It is actually closer to 96 mL. Therefore, when preparing volume/volume percent solutions, it is always better to dissolve the solute in solvent and then add additional solvent to bring the total solution volume to the desired final value.
