The number of moles of a solute per liter of solution is measured using the unit of concentration known as molarity.
Thus, The approach for resolving molarity issues is quite straightforward. This describes an easy way to figure out how molarity of a solution.
Remembering the units of molarity (M): moles per liter, is the key to calculating molarity. Calculate how many moles of the solute are dissolved in a solution's liter volume to determine its molarity.
The molarity of a solution made by combining 23.7 grams of KMnO4 with 750 mL's worth of water. You must first determine the amount of moles of the solute because this example lacks the liters or moles required to determine molarity.
Thus, The number of moles of a solute per liter of solution is measured using the unit of concentration known as molarity.

explain the concept of thekinetic molecular theory
Answer:
Kinetic Molecular Theory states that gas particles are in constant motion and exhibit perfectly elastic collisions. Kinetic Molecular Theory can be used to explain both Charles' and Boyle's Laws. The average kinetic energy of a collection of gas particles is directly proportional to absolute temperature only.

how do i set up an electron configuration
Answer:
Electron configuration can be carried out in two steps which can be:
Sublevel notation
Shell notations.
In the sublevel notation, the sequence of filling electrons into the orbitals of the sublevels are guided by some principles:
the maximum number of electrons in the orbital of sublevels are two for s-sublevel, six for p-sublevel, ten for d-sublevel and fourteen for f-sublevel. This indicates that the maximum number of electrons in an orbital is two.
Aufbau's prinicple states that sublevel with lower energies are filled up before those with higher energies.
Pauli exclusion principle states that no two electrons in an atom can have the same set of the four quantum numbers.
Hund's rule states that electrons go into degenerate orbitals singly first before pairing occurs.
Using the shell notation, numbers are used to denote the sum of electrons in all orbitals each energy level.
For an atom of Be:
Sublevel notation for the 4 electrons 1s²2s²
Shell notation 2,2
Other representation is using the electron dot structure.
