Essay text:
Molecules of stearic acid in monolayer
57.8 cm? x 1molecule = 2.8 x 1016 molecules
2.1 x 10-15 cm?
3. Moles of stearic acid in monolayer
Average drops of stearic acid to make up the monolayer = 6
Average drops of stearic solution in 1 mL = 96
ml of stearic acid in monolayer = 6 / 96 = .0625 ml
Grams of stearic acid in monolayer = .1ml x 1.4 x 10 -4 g ml = 1.4 x 10 -5 g
1.4 x 10 -5 gram stearic acid x 1mol stearic acid = 4.9 x10-8 mol stearic acid
284 g stearic acid
Avogadro's number = 2.8 x1016 molecules = 5.7 x 10 23 molecules/moles
4.9 x 10 -8 mol
