Answer:
Variability of data around the mean is best expressed through the standard deviation.
Explanation:
We have some statistical metrics, and we need to find the best measure of the variability of data around the mean.
First variable is mode. Mode of a set of data values is the value that appears most often. It means the most frequent data.
Second variable is Median. The median is a simple measure of central tendency. It is located around 50% of data range.
Third variable is standard deviation. The standard deviation is found by taking the square root of the average of the squared deviations of the values subtracted from their average value. It means, it will show the dispersion of data around the average value.
According to the definition presents for the three variables, Standard deviation is the most appropriate measure of variability of data around the mean.

Number of particles in one mole of a pure substance
Explanation:
The avogadro's constant is the number of particles in one mole of a pure substance.
- A mole is a unit of quantity of particles.
- It can be likened to a quantity of things in everyday life like a dozen, a gross etc.
- A dozen is 12 units of substance.
- A mole contains 6.02 x 10²³particles.
- 6.02 x 10²³ is called the Avogadro's number or constant.
- This was proposed by Amedo Avogadro.
- A mole is the amount of a substance that contains the Avogadro's number of particles.
- The particles are atoms, molecules, formula units, ions, electrons, protons, neutrons e.t.c
