What is the molar concentration of a solution made by dissolving 4.0g of NaOH in enough water to make 1.0 L of solution?

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).

What is it called when the concentration of a solution defined in terms of moles of solute per liter of solution?
This is a molar concentration.
What is the molar concentration of Na in a solution prepared by dissolving 100.0g of Na3PO4 in sufficient H2O to form 2.00 L of solution?
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.
What is the concentration of a 4.0 L solution that has 2.0 mol of solute?
The concentration of the solute is 0,5 molar.
How do you calculate molarity for milli molar and nano molar solution?
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
What is a 1 molar solution?
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.
What is the concentration of FeCl3 in a solution prepared by dissolving 40.0 g of FeCl3 in enough water to make 275 mL 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)

What is the Concentration of a 0.01M CaCO 3 solution?
0.01 Molar
When 0.027823 mol of lead II nitrate is dissolved in enough water to make 800 mL of solution what is the molar concentration of nitrate ions?
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.
What is the concentration of a 4.0 L solution that has 2.0 mol of solute?
The concentration of the solute is 0,5 molar.
If ferrous solution is stabilized with one molar sulfuric acid does that mean ferrous concentration is one 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.
What information is need to calculate the pH of a solution?
The molar concentration of the hydrogen ions
How do prepair normal solution of any chemical?
Normal concentration is the ratio between molar concentration and an equivalence factor.
What is the molar absorption of copper-II sulfate pentahydrate whose absorbance is 0.17 at 650nm?
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
What is the ratio of moles of absolute to liters of solution called?
You think probable to molar concentration.
What is hypothesis of a acid base titration?
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.
