The number of grams of oleic acid that is in one drop is; 8.5 × 10⁻⁶ g
From online values gotten, it is discovered that the volume in mL of oleic acid/benzene that it will take to form a monolayer is 0.424 mL.
Since we are given the concentration of the oleic acid/benzene solution is 0.02g/l. Converting it to g/mL gives 0.02/1000 g/mL.
Thus;
Number of grams of oleic acid is in one drop is;
m = 0.424 × 0.02/1000
m = 0.00000848
Approximately; m = 8.5 × 10⁻⁶ g
