Sup brahs,

Im doing an experiment for college chem and I cant figure out how to do some stuff.

Concentration of Stearic Acid : 0.11 g/L
Drops in 1 Ml of SA : 49
Volume of 1 drop = 1/49 = 0.020
Diameter of water surface in cm : 12.6 CM
Area of water surface = 39.69pi
Number of drops of SA to create monolayer : 6 drops

Grams of stearic acid per drop : 2.2 x 10^-5

So my question is;

Grams of stearic acid in one monolayer = 1.3 x 10^-4 (figured this one out)
Volume of stearic acid in one monolayer (cm3)
Thickness of layer in cm
Length of Stearic Acid in Angstroms

Thanks brahs!!
