its 100 ppm
5ml of the 1000 ppm solution in 95ml distilled water gives a 500ppm solution
ppm means the amount of solved matter(mg) in one kg of solution. most of the times we use of this equation: (x)ppm=(x)mg/1Liter
100ppm means, you need 100mg in 1oooml. Thus, for 100ml solution, you will need 10mg of methanol to make 100ppm solution.
Just take 3 grams and add this to 1000 litres (= 1,000 kg = 1,000,000 (million) grams)
how to prepare 1000 ppm solution of nickel carbonate
Make a 1 to 100 dilution of the original 1000 ppm solution. That is take 1 ml and dilute to 100 ml, or take 10 ml and dilute to 1000 ml. This will give you a 10 ppm solution.
No 100 ppm of NaCl = 100 mg NaCl/1 L = 67,87 ppm (67,87 mg/L) of Na

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.
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.
dilute it 1 in 5000. likely best done with a serial or step dilution
200 ppm solution means 200 mg/liter 200 mg = (100 *0.2)/37 = 0.540 g of 37% formaldehyde Vol of 0.540 g of 37 % formaldehyde= 0.540/1.09 = 0.496 mL of 37 % of formaldehyde Therefore: 0.496 mL/1 liter.
1 ppm is 1 mg per litre so you need to weigh out the amount of zinc sulfate that contains 10mg i.e 0.01g SO4 which is 287.4/32 =8.98125g ZnSO4-7H2O and add to a 1 lt volumetric flask and dilute with water to 1 litre.
add 2.4ml glacial aetic acid in one liter of d.m water
Preparation of PPM level standards of ethanol in waterUse the absolute alcohol to prepare the stock solutions of known concentration say for example: 100 ml of 1 g/L of ethanol solution1 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.
