This graph represents a population of molecules in a gas versus the distribution of the average velocity(speed) of its molecules
pshichka [43]

Answer:

Part A

Given that the graph is symmetrical and bell shaped, the average kinetic energy is given by the midline of graph, which corresponds to the common speed of the highest number of the population

Part B

The formula for the average kinetic energy, K.E. = (3/2)·(R/NA)·T

Therefore, the part of the graph that indicates the temperature of the sample is the average kinetic energy. K.E.

Part C

At a lower temperature, the heat is less evenly distributed and we have the distribution T2 higher than T1

never [62]
This question is about Avogadro's number.


Avogadro's number is the number is 6.022 * 10^23.


That means that 1 mol of molecules is 6.022 * 10^23  molecules, so 4 moles is 4 * 6.022 * 10^23 molecules = 24.088 * 10^23 molecules = 2.4088 * 10^24 molecules.
