A drop of oil V = 1mm³ spread over the water, forming a film with a thickness of 1 molecule and an area of 0.6 m². determine the diameter of the molecule. molecule ball.
Initial data: V (volume of oil droplet spread over water) = 1 mm3 (1 * 10-9 m3); S (area of the formed oil film) = 0.6 m2.
The diameter of the oil molecule (the thickness of the oil film) is determined by the formula: d = h = V / S.
Calculation: d = 1 * 10-9 / 0.6 = 1.67 * 10-9 m (1.67 nm).
Answer: According to the calculation, the diameter of the oil molecule is 1.67 nm.
