Molarity

Postby Elyssa Smith 4B » Wed Oct 02, 2019 6:26 pm

I know that the fraction of molarity is: moles of solution over volume of solution, but what does molarity actually represent and when would I need to calculate it?

Molarity is a concentration of moles in a solution. A bigger picture is how strong a solution is. You would need it when determining limiting reactants with aqueous solutions.

Knowing the molarity can also help you find the moles of a compound given that you know the volume and vice versa.

Molarity is the concentration of moles in a solution. Knowing the molarity of a solution is essential when you create dilutions and conduct reactions with aqueous solutions.

Molarity represents the concentration of a solution (specifically the number of moles of solute per liter of solution). You would need to calculate molarity in a wide variety of various situations, including calculating the moles of a solution, calculating the volume of a solution, calculating the moles and / or volume of a solution before and / or after dilutions, etc.

Molarity can be determined by dividing the moles of solute by the volume (in liters) of solution; molarity essentially just represents how concentrated a particular solution is.

Molarity is relevant when dealing with solutions. By doing molarity calculations, you can determine the moles of solute and how you may need to dilute the solution.

Molarity can be used to figure out the concentration of the solute in the solution. It can be calculated when doing a lab to get the correct concentration of a solution. it is also helpful if given molarity as a variable you can either solve for Liters or moles of a substance depending on what else is given.

Molarity is used to calculate the concentration of of molecules in a solution. It is useful when you want to find the strength of a solution or when you are given a question asking you to dilute a solution and need to use the MV(initial)=MV(final) equation.

Molarity is a measure of concentration and is usually used when the solvent is water and/or the amount of solute is relatively small compared to the amount of solvent used. Later on, we'll probably learn molality, which is a better concentration when calculating things like temperature changes or when the solvent of the solution is not water.
