∙ 11y agoMolarity (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.

∙ 11y agomolarity 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
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
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
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).
The quantity that serves as a conversion factor between mass and number of moles is the molecular mass.
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.
The molarity is 5,55.
To find the moles of solute, multiply the volume of the solution in liters (1.25 L) by the molarity of the solution (0.75 mol/L). Therefore, the moles of NaNO3 in 1.25 L of 0.75M solution is 0.9375 moles.
The molarity is 0,025.
The molarity is 0.718 moles/litre.
This molarity is 1,59.
Molarity is moles of solvent divided by liters of solution, so 6.42 / 1.75 = 3.67M.
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.
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.
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.
The answer is 0,625 moles.
To calculate the molarity of the solution, first convert the mass of HCl to moles using its molar mass. Then, divide the number of moles by the volume of the solution in liters (500 cm3 = 0.5 L) to get the molarity.
