Question
Calculate the density of distilled white vinegar
Mass = 29.03 volume=30mL
density = 0.9676 = 0.97 g/ml
3) The concentration 5% (w/v) means that 5g of acetic acid (solute) are present in 100mL of the solution. Using the density you determined in the previous problem, determine the mass of water (solvent) in 100mL of the solution. Follow the guided steps below
a) Determine the mass of 100mL of the solution by using the density. Express your answer in three significant figures
b) the mass of the solution should be the sum of the mass of the solvent and the mass of the solute. Now determine the mass of the solvent.
Explanation / Answer
mass of solute present = 5 g
volume of solution = 100 mL
density = mass/ volume
0.97 = mass / 100
mass of solution = 97 g
mass of solution = mass of solute + mass of solvent
97 = 5 + mass of solvent
mass of solvent = 92.0 g
