THE MEANING OF % IS
1 gm of substance in 100 mL of solvent.(w/v)
so you can prepare 1 % sodium citrate by dissolving 1.0 g of Sodium citrate in to 100 ml of water.
Benedict's solution typically contains copper(II) sulfate, sodium citrate, and sodium carbonate. The exact composition can vary, but a common formulation is 17.3 g copper(II) sulfate, 100 g sodium citrate, and 173 g sodium carbonate per liter of water.
Dissolve 30-40 g of sodium chloride in 1 L of water.
You need 50 g of this drug.
Yes, Bacillus amyloliquifaciens typically shows a positive reaction for citrate utilization due to its ability to metabolize citrate as a carbon source. This can be confirmed using citrate utilization tests in a laboratory setting.
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 a 1.25 M solution of sodium citrate, dissolve 294.1 grams of sodium citrate dihydrate powder in 1 liter of water. Mix well until the powder is completely dissolved. Adjust the volume if necessary to reach exactly 1 liter.
Sodium citrate is composed of around 13% sodium by weight. This means that 1 gram of sodium citrate contains roughly 130 milligrams of sodium.
You would wan to dilute the trisodium citrate in distilled water to create a 1% solution. So if you wanted 100mL of solution, you would mix 1mL of trisodium citrate with 99mL of distilled sterile water.
Benedict's solution typically contains copper(II) sulfate, sodium citrate, and sodium carbonate. The exact composition can vary, but a common formulation is 17.3 g copper(II) sulfate, 100 g sodium citrate, and 173 g sodium carbonate per liter of water.
To prepare Benedict's reagent, dissolve 17.3 g of sodium citrate and 1.72 g of anhydrous sodium carbonate in distilled water. Then add 0.5 g of copper sulfate pentahydrate and heat the solution until the salts dissolve completely. Adjust the volume to 1 L with distilled water, filter the solution if needed, and store in a cool, dark place.
16.5g 97% pure NaOH pellets dissoved in 1 litre of distilled
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.
No.
To prepare a 1 ppb sodium solution from a 1000 ppm sodium standard, you can dilute 1 mL of the 1000 ppm sodium standard with 999 mL (or 999 g) of solvent. This will result in a final solution with a concentration of 1 ppb, as 1 mL is equivalent to 1 mg in this case.
Each 200ml contains- 1) Sodium Chloride= 250mg 2) Potassium Chloride= 30 mg 3) Sodium Citrate = 580 mg Calculate osmolarity of Sodium, Poatassium and Chloride

To prepare a 3% solution of sodium hydroxide, you can dissolve 3 grams of sodium hydroxide pellets in 100 mL of distilled water. Ensure proper safety precautions are taken when handling sodium hydroxide as it is a caustic substance that can cause burns.
