The moles of potassium that you would need to prepare 1200 g of 5% potassium sulfate solution is 1.538 moles
calculation
calculate the mass potassium using the below formula
%M/M = mass of the solute(potassium)/mass of the solvent (potassium sulfate solution)
let the mass of potassium be represented by Y
then convert % into fraction = 5/100
5/100 = Y/1200
cross multiplication
100y = 6000
divide both side by 100
Y= 60 g
moles of potassium =mass/molar mass
= 60/39=1.538
The same sample of gas at different temperatures shows that at low
temperatures, most molecules have speeds close to their average
speed.

What does the Maxwell-Boltzmann distribution graph show?</h3>
Put simply, a Maxwell-Boltzmann distribution graph shows how the energy of gas particles varies within a system.
This is solely a measurement of the speeds of particles because kinetic energy is directly related to speed.
The Maxwell-Boltzmann distribution in chemistry is the subject of this article.
We will begin by describing how to read a graph of the Maxwell-Boltzmann distribution. This will involve taking a closer look at things like the typical energy and the most likely energy.
The graph will then be changed under various circumstances, such as when a catalyst is added or the temperature is raised.
The Maxwell-Boltzmann distribution, which we previously mentioned, is a probability function that depicts the distribution of energy among the particles of an ideal gas. (For more information on this topic, see Chemical Kinetics.)

7. An exothermic reaction
8. The bonds are forming
Answer:
27.7 × 10²³ atoms
Explanation:
Given data:
Number of moles of Potassium = 4.6 mol
Number of atoms = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
18 g of water = 1 mole = 6.022 × 10²³ molecules of water
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
For 4.6 moles of K:
One mole = 6.022 × 10²³ atoms
4.6 mol × 6.022 × 10²³ atoms= 27.7 × 10²³ atoms
