Determining the Dimensions of a Molecule
Volume of PURE oleic acid (show calculations below) 0.027ml___ mL
0.027ml = 12 drops * 0.0152ml (one drop)
Number of oleic acid molecules in the slick (show calculations) 1.62594*1022
0.027ml * (6.022*1023) = 1.62594*1022
Surface area of the oil slick (show calculations) 237.72____ cm2
3.14(8.701cm)2 = 237.72
Cross sectional area of an oleic acid molecule (show calculations) __________ cm2
Depth of the oil slick (show calculations) __________ cm
Diameter of an oleic acid molecule (show calculations) __________ cm
Length of an oleic acid molecule __________ cm
Homework Answers
1- volume of the oleic acid molecule= volume of the pure oleic acid / total molecule
=0.027/1.625x1022=1.66x10-24mL=4/3
r3
r=7.34x10-9cm
cross sectional area=
r2=3.14x(7.34x10-9)2=1.69x10-16cm2
2- depth of the oil slick=volume of the oil slick/ cross sectional area
=0.027/237.72=1.14x10-4cm
3- diameter of an oleic acid molecule= 2r =2x7.34x10-9=1.468x10-8cm.
4- length of the oleic acid molecule=diameter=1.468x10-8cm

A calibrated pipet (95 drops/mL) delivers 12 drops of stearic acid solution. (1.5x10^-4 g/mL) to give a monolayer with a diameter of 12.5 cm. Calculate the surface area of tge monolayer, the moles of stearic acid (284 g/mol) in the monolayer, the number of stearic acid molecules in the monolayer, and the apparent volume & cross-sectional area occupied by each molecule.
