Best Answer

Molarity (M) = moles of solute (mol) / liter of solution (L)M = mol / L

You have 250 mL of Solution, which is

250 mL x ( 1 L / 1000 mL ) = ( 250 / 1000 ) L = .25 L


Solute is just what's dissolved

Solvent is just what it's being dissolved in

Solution is the solute and the solvent.


M = mol / L

M = 0.65 mol / 0.25 Liters = 2.6 mol/L


The two numbers that you are given, 0.65 moles and 250 mL both have two significant figures, and the answer is two significant figures (2.6 mol/L)


Therefore the answer is 2.6 mol/L.

Definition of molarity and its equation?

molarity is the number of moles dissolved per volume of a solution in dm cube molarity=mass of solute in gram __________________ 1 * _________________ molecular mass of solute volume of solution in dm cube OR molarity=no.of moles ________________ volume of solution in dm cube


What is the formula of morality?

Unfortunately morality has no equation :-( It would be much simpler if morality would be clearly defined and all men would be in agreement about it. If there is a typing error it is possible that you would like to say molarity (m). It is the measure of the concentration of a solute in a solution and it is the ratio between the number of moles of the solute M (number of molecules divided the Avogadro number that is about 6.022 1023) and the solution volume V. Thus m=M/V


How many grams of NaCl are in 5.00 M solution?

You haven't given the volume of solution. M means moles per liter. First off you divide 5 by 1000 and multiply by the amount of mls you have to find out how many moles that you have. then multiply by molecular weight of NaCl


What does square brackets mean in chemistry?

Isn't this the wrong section? >_> Square brackets generally refer to the concentration of whichever element or compound. For example [A] would refer the the concentration of A (generally calculated in moles/Liter or molarity).


What quantity serves as the conversion factor between the mass of a sample and how many moles the sample contains?

The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.

A solution contains 85.0 g of NaNO3 and has a volume os 750 mL find the molarity of the solution?

First, convert the mass of NaNO3 to moles using the molar mass of NaNO3. Then, calculate the molarity by dividing the moles of NaNO3 by the volume of the solution in liters. Molarity (M) = moles of solute / volume of solution in liters.

What is the molarity of a solution that contains 6.42 moles of lithium nitate in 1.75 liters of solution?

Molarity is moles of solvent divided by liters of solution, so 6.42 / 1.75 = 3.67M.


What is the molarity of a solution that contains .202 mol KCI in 7.98 L of solution?

The molarity of the solution is calculated by dividing the moles of solute (KCl) by the volume of solution in liters. In this case, molarity = 0.202 mol / 7.98 L ≈ 0.0253 mol/L.


What is the molarity of a solution where 4.00 moles of Potassium Chloride is dissolved in 3.00 L of solution?

The molarity can be calculated by dividing the moles of solute by the volume of solution in liters. In this case, molarity = 4.00 moles / 3.00 L = 1.33 M.


What is the molarity of a 3.0 liter solution that contains 0.45 moles of solute?

The molarity of a solution is calculated by dividing the moles of solute by the volume of the solution in liters. In this case, the molarity would be 0.15 M, which is calculated by dividing 0.45 moles by 3.0 liters.
