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.

The rest you may do on your calculator and record in Data Table 1, above. Volume KOH: # drops KOH x average # drops H2O/mL Mass KHP/L (g/L): 1.02 g KHP/100 mL x 103 mL/L (This will be the same for all trials!) Molarity KHP (mol/L): M1V1 = M2V2 M1 = molarity KOH (0.1 M) V1 = volume KOH titrated (A) M2 = ?? m/L KHP V2 = 2.0 mL KHP M2 = M1V1/V2
