Use the absolute alcohol to prepare the stock solutions of known concentration say for example: 100 ml of 1 g/L of ethanol solution
1 g/L is equal to 1000 mg/L which is 1000 ppm. Otherwise the concentration of the 100 ml stock solution is 1000 ppm.
Next step: Perform serial dilution procedure to prepare the required ppm level of ethanol standards. For performing the serial dilution, u have to convert the weight of ethanol into volume by dividing the weight by density of ethanol. Density of ethanol = 789 kg/cu.m or 789 g/L.

How do you prepare 100 ppm fluoride standard from sodium fluoride?
To prepare a 100 ppm fluoride standard from sodium fluoride, you would dissolve an appropriate amount of sodium fluoride in a known volume of water. For example, to make 1 liter of 100 ppm fluoride solution, you would dissolve 0.1 grams of sodium fluoride in 1 liter of water.
How can you prepare 1ppb from1000ppm sodium standard?
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.
How can you prepare solution 0.2 ppm from 1000 ppm?
To prepare a 0.2 ppm solution from a 1000 ppm solution, you would need to dilute the 1000 ppm solution by adding 5000 parts of solvent for every 1 part of the 1000 ppm solution. This means mixing 1 part of the 1000 ppm solution with 5000 parts of solvent to achieve a 0.2 ppm concentration.
How prepare ppm report?
Assuming that you are referring to PPM as (parts per million), you can prepare a report on the solution, depending on the different ingredients that are involved and quantity of each substance present.
How do you prepare solution in ppm?
You prepare a primary solution then dilute portion of your solution down to the required concentration. For example, you want a 10 ppm salt solution (10 mg/L), you dilute 1 g of salt in 1 L of water you get 1000 ppm salt solution. You take 10 ml of your salt solution (0.01 g salt in 10 g) and add in additional 980 ml of water then you get a 10 ppm weight solution.

What is the LEL of ethanol?
The Lower Explosive Limit (LEL) of ethanol is approximately 3.3% volume concentration in air. This means that if the concentration of ethanol in the air is below 3.3%, it is too low to ignite and sustain combustion.
How can you prepare solution 0.2 ppm from 1000 ppm?
To prepare a 0.2 ppm solution from a 1000 ppm solution, you would need to dilute the 1000 ppm solution by adding 5000 parts of solvent for every 1 part of the 1000 ppm solution. This means mixing 1 part of the 1000 ppm solution with 5000 parts of solvent to achieve a 0.2 ppm concentration.
How do you get iodine from a solution of iodine in ethanol?
As we know PPM=mg/Kg, if d=1 so PPM=mg/L At first we must calculate the densty of ethanol in kg, so when we use 0.5L of ethanol it means : 0.789 kg/L = x kg/0.5L : x=0.394 Kg For a 100 ppm solution of iodine in 0.5 L of ethanol we have 100=mg I2 /0.394 kg so mg I2 = 39 mg S.Pourmand M.Sc.

How do you prepare 2 ppm solution of nickel nitrate?
To prepare a 2 ppm solution of nickel nitrate, you would dissolve 2 grams of nickel nitrate in enough water to make 1 liter of solution. This will result in a solution where there are 2 parts of nickel nitrate for every 1 million parts of water.
How do you prepare ppm solution from solid?
To prepare a parts per million (ppm) solution from a solid, you would first need to accurately measure the mass of the solid compound. Then, dissolve this solid in a known volume of solvent to make a specific concentration solution. Finally, calculate the ppm concentration by dividing the mass of the solid compound by the total mass of the solution and converting it to ppm.
