The concept to be used in order to determine the diameter of the second cell in the photograph is that of the ratio and proportion. The ratio of the first set of measurements should be proportional (equal) to the ratio of the second set.
Ratio of first set of diameters,
r = diameter of Cell A / diameter of Cell B
r = 12 micrometers/20 micrometers
r = 3/5
If we let D be the diameter of the cell B in photographs,
r = 3/5 = 15 cm/x cm
The value of x from the equation is 25. Hence, the diameter of cell B is 25 cm.

Answer:
A single distillation cycle is enough to separate the mixture. ... Simple distillation is the method used to separate substances in mixtures with significantly different boiling points, while fractional distillation is used for mixtures containing chemicals with boiling points close to each other.
