How 1000 ppm solution of arsenite prepared from sodiumarsenite?
Wiki User
∙ 12y ago
1 ppm means 1 mg/l so 1000 ppm means 1000 mg/l or 1gm/l ,
FW of sodium arsenite NaAsO2 is 130 ans As is 75
75 gm of arsenite is present in 130 gm sodium arsenite
1 gm---------------will be---------130/75= 1.73 gm
so if 1.73 gm of sodium arsenite is present in 1 litre of water it makes 1000 ppm solution of arsenite

How do you prepare a primary standard solution of 0.0500 M sodium carbonate?
use the equation that is standard: 1000 ml 1 M solution= (MOLECULAR WEIGHT) X ml 0.05 M solution = ((MOLECULAR WEIGHT)*X*0.05)/1000
What is the molarity of a 1000 ml solution containing 65.12 g of potassium cyanide?
1M
What is the molarity of the 5.60 mols of sodium carbonate in 1500 ml of solution?
Molarity is moles per litre. You need to divide the moles by 1500 and multiply by 1000. 5.6/1500*1000 is 3.73333 molar.
How many moles of barium chloride are in 1.5 liter of a 0.256 molar solution?
.256 molar= 256 mols of solute per 1000ml of solution. Since there are 1000ml in 1L, there are 256 mols of BaCl2 for every liter. Multiply this by 1.5 and you get a total of 384 mols of BaCl2 in 1.5L of a .256 molar solution
How much kcl require for prepaire 3M kcl?
Molar mass of KCl = 74.55g/mol.ie, if you dissolve 74.55g KCl in 1litre (1000 ml) of water, it will be 1M KCl solution.If you want to make 3M KCl solution,Dissolve 3 ×74.55 = 223.65g KCl in 1litre (1000 ml) of water.If you want to make different molar solutions of KCl, just calculate as per below given equation.Weight of KCl to be weighed =Molarity of the solution needed × Molecular weight of KCl (ie, 74.55) × Volume of solution needed in ml / 1000.To prepare 3M KCl in 1 litre, it can be calculated as follows,3 mol × 74.55 g/mol × 1000 ml / 1000 ml = 223.65gByPraveen P Thalichalam, Kasaragod (Dist), Kerala.
What is the concentration in ppm of 1gmL solution of sodium arsenite?
Assuming you really mean 1 g/ml (which is very high), then ... convert 1 gm/ml to mg/liter to get ppm1 g = 1000 mg 1 ml = 0.001 L 1000 mg/0.001 L = 1,000,000 mg/L = 1,000,000 ppm
What is the molarity of a solution prepared by dissolving 15.8 g of glucose of MW 180 amu in 169 mL of solution?
15.8/180 is 0.08777778 moles in 169ml. divide by 169, x 1000 (per litre) is 0.5194M
What percent is a solution containing 1000 mg in 1000 ml in total?
The percentage of a solution containing 1000 mg in 1000 ml is 100 percent.
What is the dilution of 1000 ppm to 500 ppm?
5ml of the 1000 ppm solution in 95ml distilled water gives a 500ppm solution
What are the top 5 deadliest toxins?
"The dose makes the poison"Potencies of PoisonsAgent Lethal doseBotulinum toxin 0.05 mgRicin 0.5 mgStrychnine 100 mgSodium arsenite 200 mgSodium cyanide 250 mgThallium 1000 mg
How many molar is 1 mili molar?
1 M is equal to 1000 mM. Calculating molarity is important in biochemical and molecular experiments. Normally 10 X or 20X stock solution are prepared from which the working solutions are diluted as per the need of the concentration (in mM)

How do you prepare 1000 ppm chloride solution from NaCl?
What volume of this solution do you desire? Let's say you want to make 1 liter of such a solution. You would weigh out 1 gram (1000 mg) of NaCl and dissolve it in enough water to make a final volume of 1 liter (1000 ml). Since 1000 ppm means 1000 mg/liter, this is how you make 1 liter of that solution. For larger or smaller volumes, adjust appropriately.
