Question: When examining the suspended gamboge droplets under a microscope, their average numbers in the layers separated by the distance h = 40 m were found

When examining the suspended gamboge droplets under a microscope, their average numbers in the layers separated by the distance h = 40 μm were found to differ by η = 2.0 times. The environmental temperature is equal to T = 290 K. The diameter of the droplets is d = 0.40 μm, and their density exceeds that of the surrounding fluid by A 9 = 0.20 g/cm 3. Find Avogadro's number from these data.
