You do not need especially 25 grams to prepare 1.0 Liter 0.1N Na2S2O3-solution.
It depends what substance is used: Na2S2O3 orNa2S2O3•5H2O (more common, called hypo).
Molar masses are different, 158.11 g/mol for Na2S2O3 or(158.1 g/mol + 5*18.02 = ) 248.2 g/mol for Na2S2O3•5H2O respectively.
To get the 0.10 N solution you'll need 15.8 gram or 24.8 gram respectively, dissolve it togather with 1 gram of disodium carbonate, and add up to 1.0 Liter (freshly boiled) water, let stand overnight and filter on fine grade paper.
To prepare 0.01N sodium thiosulfate per Indian Pharmacopoeia (IP) standards, dissolve 25.3 grams of pure sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water to make 1000 ml of solution. This solution will have a normality of 0.01N.
To prepare a 0.01N solution of sodium thiosulfate, dissolve 2.48 grams of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in distilled water and make up the solution to 1 liter. This solution will be approximately 0.01N in strength. Remember to accurately weigh the compound and use a volumetric flask for precise dilution.
To prepare a 0.01N solution of sodium metabisulfite, you would need 2.31 grams of sodium metabisulfite per liter of solution.
To calculate the grams of sodium thiosulfate needed, first determine the molar mass of Na2S2O3 (158 g/mol). Step 1: Calculate the number of moles needed using the formula: moles = Molarity * Volume (in liters) moles = 0.025 * 2 (since 2000 ml is 2 liters) = 0.05 moles Step 2: Calculate the grams needed using the formula: grams = moles * molar mass grams = 0.05 * 158 = 7.9 grams Therefore, you would need 7.9 grams of sodium thiosulfate to make 2000 ml of a 0.025N solution.
To prepare a 1 N solution of sodium bicarbonate, dissolve 84 grams of sodium bicarbonate in enough water to make 1 liter of solution. This will give you a 1 N (equivalent to 1 mol/L) concentration.

This solution will be approximately 0.01N in strength. Remember to accurately weigh the compound and use a volumetric flask for precise dilution.
To get 100g of solution: 10g of sodium thiosulfate + 90g of water.
To prepare a 0.1N Na2S2O3 solution, dissolve 24.98 grams of Na2S2O3·5H2O (sodium thiosulfate pentahydrate) in distilled water and dilute to 1 liter in a volumetric flask. This will give you a 0.1N (normal) solution of Na2S2O3.
To prepare N 80 thiosulfate, dissolve 80 grams of sodium thiosulfate pentahydrate (Na2S2O3·5H2O) in enough distilled water to make a final volume of 1 liter. Stir the solution until the thiosulfate is completely dissolved. Ensure that the solution is mixed well and store it in a properly labeled container. Always follow safety protocols when handling chemicals.
To prepare a 0.01N solution of sodium metabisulfite, you would need 2.31 grams of sodium metabisulfite per liter of solution.

To prepare a 1 N solution of sodium bicarbonate, dissolve 84 grams of sodium bicarbonate in enough water to make 1 liter of solution. This will give you a 1 N (equivalent to 1 mol/L) concentration.
To prepare a 1% solution of sodium citrate, you would mix 1 gram of sodium citrate with 99 grams of water (for a total of 100 grams solution). Stir the mixture until the sodium citrate is fully dissolved in the water.
600 mL of 0,9 % sodium chloride: 6 x 0,9 = 5,4 grams NaCl
To calculate the total amount of sodium chloride needed for a 13 L solution at 4 grams per liter, multiply the concentration by the volume of the solution: 4 grams/L x 13 L = 52 grams of sodium chloride. Therefore, you will need 52 grams of sodium chloride to make the 13 L solution.
In standard methods it says to dissolve 3.5 g sodium thiosulfate in water and dilute to 1 L. Use 1 ml reagent to remove 1 mg/L residual chlorine in 500 ml sample.
