    To make a 1 Molar solution of NaOH, you would put 40.01 grams of NaOH into a volume of water and then add water to reach 1 liter total volume.

  2. Guest18873161
    we have formula = M = M*mol wt*1000/1000 so 1*40*1000/1000 = 40g dissolve 40g of NaOH in 1000ml to give 1M solution.
  3. Guest18873161
    formula of the molarity = M * Mol weight * volume to be made m = 0.1 , Mol wt = 40 , volum to be mad = 1000 or 500 put the valus in for = 0.1 * 40 *1000 = 400g take and dissolve in sufficent volume = 0.1 * 40 * 1000 = 200 g take and dissolve in sufficinet volume hope that will be the answer...

    how do i make 0.1 molar solution of NaOH from 1 molar solution

    Just dissolve 40 grams oh NaOH on water.

    Hi, First of all,you need to understand what molarity and normality are. Molarity refers to the number of molecules of a substance in a solution; a 1M solution contains 1 mole (6.02 x 10^23 molecules or particles) of the substance in 1 liter of solution. Normality refers to compounds that have multiple chemical functionalities, such as sulfuric acid, H2SO4: a 1M solution of H2SO4 will contain only one mole of H2SO4 in 1 liter of solution, but if you titrate the solution with base, you will find that it contains two moles of acid. This is because a single molecule of H2SO4 contains two acidic protons. Thus, a 1M solution of H2SO4 will be 2N. Now, for your specific question: NaOH contains only one significant chemical functionality, which is the basic hydroxide, OH-. So, for NaOH solutions, molarity and normality will be the same thing. So, a 1.0 N solution of NaOH in water is also a 1.0 M solution of NaOH in water, and a 0.1 N solution of NaOH in water is a 0.1 M solution of NaOH in water. How do you make these? The first thing you need to know is the mass of a mole of NaOH. This is just its molecular weight: 40.0 g/mol. (That's what a molecular weight means: the mass in grams of one mole of the substance.) So, to make a 1.0 M (= 1.0 N) solution of NaOH in water, you will want to weigh out 40.0 grams of NaOH, dissolve it in about 0.8 liters of water, and then add water to the solution to take the total volume up to exactly 1.0 liters. You would do the same thing to make a 0.1 M (= 0.1 N) solution: weigh out 0.1 mole of NaOH (= 4.0 g), dissolve it in water, and add enough water to make the total volume equal to exactly 1 liter. If you don't want exactly on liter of these solutions, then you need to change the amounts by the same factor: if you need 0.5 liters of a 1.0 M solution, you use 0.5 moles of the substance and enough solvent to make the solution volume exactly 0.5 liters.
