MOLARITY

Postby 805098281 » Fri Oct 05, 2018 12:08 pm

Could someone please clarify molarity to me and how it is used in experiments. I don't understand the importance of it..

Molarity is basically the measure of the concentration of a solution in moles of a solute (which is the substance being dissolved) over the liters of solution (which is the substance the solute is being dissolved in). Something helpful about molarity is that if it is given, it can be used to find unknown amounts of solvent or solute.

Molarity is a measure of the concentration of a chemical species in a solution. It is telling you how many moles of a chemical species there are in a single liter of solution. It can be used to find many different values in relation to a chemical reaction if it is done in a solution.

Molarity is essentially a quantity used to define the concentration of a substance in solution. It can be used as a conversion factor to determine the moles of a substance or volume of a substance.

Molarity is moles of solute in liters of solution. The unit for molarity is mol/L.

Molarity is also important for dilution problems because it can be used in the equation (Minitial)(Vinitial)=(Mfinal)(Vfinal) to determine concentrations, volumes, or moles of the solute before or after the solution has been diluted.

Molarity is the number of moles of solute per liter of solution and can be calculated by Molarity= mol solute/L of solution

Molarity is the moles of solute divided by the liters of the solution. You can use it during dilution calculations!

With regards to molarity when diluting a solution, it is important to remember that the moles of solute remain the same. The unknown volume or mass can be computed by plugging known values into: M(initial)xV(initial) = M(final)xV(final)

Molarity's importance lies in how it defines the concentration of the solution and acting as a measurement of moles of solute per liter of solution. It is a big part of dilution calculations since moles of solute stay the same, so it is easy to calculate the molarity when knowing how much solution was added.

Molarity is the measure of concentration of a substance in a solution and is used to calculate concentrations, volumes, or moles of a solution, using M(initial)xV(initial) = M(final)xV(final)
