Iron (III) chloride has the molecular formula of FeCl3. Its molecular weight is 162.2 grams per mole. Concentration is moles of solute divided by volume of solution. Therefore, the answer is .224 moles per liter.
what is the molarity of a solution prepared by dissolving 36.0g of NaOH in enough water to make 1.50 liter of solution?
Look up or calculate the molecular weight/molar mass of FeCl3. Then... 40.0 g FeCl3/MW FeCl3/0.275 L = M (concentration of FeCl3 in solution)
The molarity of KNO3 is 0,058.
The molarity of a solution made by dissolving 23,4 g of sodium sulphate in enough water to make up a 125 mL solution is 1,318.
4.0 (g/L) / 40 (g/mol NaOH) = 0.10 (mol/L NaOH) = 0.10 M
Molarity=Moles of solute/Liters of solution1.350 g KOH = 0.02406 mol KOH0.02406 mol/0.2500 L =0.09624 M of KOH
Dissolving takes place when you are trying to make a solution out a mechanical mixture by adding a solute (something that gets dissolved) and a solvent (something that does the dissolving) together and when there is enough solvent to dissolve the all of the solute. When all of the solute is dissolved it becomes a solution which usually appears to be clear.
[ 100 (gNaOH) / 40.0 (g/molNaOH) ] in 1.65 L is 1.151 M = 1.515 mol/L
There is not enough information to answer the question. It depends on the salt concentration.
Both must be in solution, aqueous, to fit the definition, which is; an acidic solution has enough hydronium ion concentration to hydroxide concentration to have a pH lower than 7.0, while a basic solution has enough hydroxide ion concentration to be at a pH higher than 7.0. An acid and base are different in definition. Subtle, but a real difference.
to make the solution basic enough so that NH be prepared for Fmoc protection
molarity = no. of moles of solute/liter of solution no. of moles of I2 = mass in grams/molar mass = 4.65/253.81 = 0.01832 mol M = 0.01832 mol/0.235 L = 0.0780 mol/L
Get moles sodium sulfate first.15.5 grams Na2SO4 (1 mole Na2SO4/142.05 grams) = 0.1091 moles Na2SO4Now,Molarity = moles of solute/ Liters of solution ( 35 ml = 0.035 Liters )Molarity = 0.1091 moles Na2SO4/0.035 Liters= 3.1 M Na2SO4 solution==================
Not necessarily. The pH of a solution depends on the strength of the acid and its concentration. Some acids at the stronger end of weak acids can form a solution with a pH of 1 at a high enough concentration.
Random thermal motion is enough to cause a gas to leave a solution, particularly when the concentration of that gas in the surrounding atmosphere is less than it is in the solution diffusion process, moving from higher concentration to lower concentration. Entropy drives such processes.
White Cornstarch is clear, but it may make your solution a bit hazy if it high enough concentration. the color of cornstart sulotion is white
Depend on the kind of concentration it is expressed in. For a 1. 0.001 Molar solution, dissolve 0.001 mols of solute in enough solvent to obtain 1L of solution 2. 0.001 molal solution, dissolve 0.001 mols in 1kg of solution.
