Based on the volume and density of one drop of the solution, the mass of the oleic acid is 0.000001 g.
The mass, volume and density of a solution are related by the formula given below:
density = 0.02 g/L
Volume of 1 drop = 0.05 mL
Converting volume in mL to L
volume = 0.05 × 1 L/1000 mL
volume = 0.00005 L
Then;
mass = 0.00005 L × 0.02 g/L
mass = 0.000001 g
Therefore, the mass of the oleic acid is 0.000001 g.
