(a) too low; molarity NaOH is lower concentration (through dilution with the drops of distilled water remaining in the buret) than standard leading to a higher volume used in titration, since MBVB = molA and 0.500 g/molA = molar mass, then a larger denominator gives a result that is too small.

Solution Composition - Mass Percent. Mass percent – describes a solution’s composition. expresses the mass of solute present in a given mass of solution. Example – A solution is prepared by mixing 1.00g of C2H5OH, with 100.0g of. H2O. Calculate the mass percent of ethanol. Solution Composition – Molarity. Molarity – measure of ...

Mass of water = mass of solution – mass of NaOH = 1000 g – (0.300 mol)(40 g/mol) = 1000 g – 12 g = 988 g. Molality = 0.300 mol/0.988 kg = 0.304 m. Notice that the molality is a little bigger than molarity. Why are these two numbers similar and why is molality always greater than molarity?

Preparation of % mass/volume solutions is presented here. Keep in mind that a 1% solution contains 1 g of solute in a total volume of 100 mL. Use the % Mass/Volume Equation shown below to calculate the mass of each solute needed for a solution at some volume. Notice that as with preparing mass/volume solutions, the math is relatively simple.
