C1V1 = C2V2
4 x .04 = 1 x V2
V2 = (4 x .04)/1
= 160mL
Therefore the volume of water that needs to be added is 120mL (minus the original volume).
4.0 (g/L) / 40 (g/mol NaOH) = 0.10 (mol/L NaOH) = 0.10 M
This is a molar concentration.
The molarity of that solution is 0.82, based on sodium phosphate's molar mass and the given volume of solution. Since there are three sodium ions for every one formula unit of sodium phosphate, the molar concentration of Na+ ions is 0.82(3)=2.46.
The concentration of the solute is 0,5 molar.
The term molar it refers a form to know the concentration of a solution, and it is equivalent to a molar unit in a litre of solvent 1 Molar (1M) = 1 mole (molecular weight from the structure you are interested in) / 1000 mL or 1 L. Milimolar is the thousandth part from a solution 1M
Molar solution, commonly called molarity, is the amount of amount of substance in a certain volume. Typically it is measured in moles per litre. A 1 molar solution means there is one mole of substance per one litre. This can also be called a one mole concentration 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)
This is a molar concentration.
The molarity of that solution is 0.82, based on sodium phosphate's molar mass and the given volume of solution. Since there are three sodium ions for every one formula unit of sodium phosphate, the molar concentration of Na+ ions is 0.82(3)=2.46.
0.01 Molar
The formula of lead (II) nitrate is Pb(NO3)2. This shows that in any solution of lead nitrate only, the molar concentration of nitrate ions will be twice as much as the molar concentration of lead (II) nitrate. Molar concentration is defined as number of moles per liter of solution, and 800 mL is the same as 0.800 liters. Therefore the molar concentration of nitrate ions in the specified solution will be 2(0.027823/0.800) or 6.96 X 10-2 . Only three significant digits are justified because that is the number of digits in 800.
The concentration of the solute is 0,5 molar.
Not necessarily or even usually. The term "one molar" refers to the concentration of the acid added and does not have anything to do with the concentration of ferrous ions.
The molar concentration of the hydrogen ions
Normal concentration is the ratio between molar concentration and an equivalence factor.
Depends on the length the light traveled through the solution and the solution concentration. molar absorption = absorbance/(length x concentration) length is typically in cm and concentration is typically in mol/L
You think probable to molar concentration.
to determine the concentration of the unknown solution and to determine the molar concentration of acetic acid in a sample of vinegar by titrating it with a standard solution of NaOH.
