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.
What is the molarity of a solution that has 2.5 moles of NaNO3 in 0.45 L?
The molarity is 5,55.
What is the molarity of a solution that contains 0.202 moles KCl in 7.98 liters of solution?
The molarity is 0,025.
What is the molarity of 5 L solution that contains 3.59 moles of solute?
The molarity is 0.718 moles/litre.
What is the molarity of a solution that contains 4.53 moles of lithium nitrate in 2.85 liters of solution?
This molarity is 1,59.
What is the molarity of a solution that contains .202 mol KCI in 7.98 L of solution?
Molarity = moles of solute/Liters of solution Molarity = 0.202 moles KCl/7.98 Liters = 0.253 M KCl solution ================
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 31.0 grams of HCl in 500cm3 of solution?
31 grams HCl (1mol/36.458g ) = 0.850 moles 500cm^3 = 0.50 Liters Molarity = moles of solute/liters of solution Molarity = 0.850mol/0.50L = 1.7 Molarity
What is the molarity of a solution where 4.00 moles of Potassium Chloride is dissolved in 3.00 L of solution?
The molarity of a solution given by the number of moles divided by the volume it contains. Hence, the molarity of KCl is 4.00/3.00 = 1.33 mol/L.
What is the molarity of a solution that contains 10.0g of NaOH in 400.0 ml of NaOH of solution?
The answer is 0,625 moles.
What is the molarity of a solution that contains 345 moles KCL in 8.6 L solution?
.487 Kl
What is the molarity of a solution that contains 0.55 moles of a substance dissolved in half a liter of solution?
Molarity means moles per litre. You have to keep that same ratio. i.e. .55moles in 0.5 litres is the same as 1.1 moles in a litre. Therefore the molarity is 1.1 molar.
What is the molarity of a 3.0 liter solution that contains 0.45 moles of solute?
0.15 M
