There are 1 mg for each kilogram of solution you have.
1?
1 mg =1/1000 or 0.001 gram1 gram = 1000mg1 mg = 1 mg * 1 gram/1000mg = 1/1000 or 0.001 gram
1000 mcg / 100 mg = 1 mg/ 100 mg = 0.011000 mcg / 100 mg = 1 mg/ 100 mg = 0.011000 mcg / 100 mg = 1 mg/ 100 mg = 0.011000 mcg / 100 mg = 1 mg/ 100 mg = 0.01
1000 mg, for every 1000 mg equals 1 g.
There are 0.120 g in 120 mg. 1 g = 1000 mg 1 mg = 0.001 g
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
if it is water 1000 ppm = 1 mg/ml
ppm by volume is "parts per million" by volume as opposed to ppm by weight. ppm by volume and ppm by weight are not the same thing It has been suggested that the drinking water in West Hampshire be adultery with 1 ppm by volume of fluoride. This is an example of ppm by volume
1 ppm = 1 mass part per 106 mass parts:So 1 mg in 106 mg = 1.0*106 mg = 1.0*103 g = 1.0 kg200 ppm = 200 mg per kg, in water 1.0 kg = 1.0 LitreSo 200 mg/L
No 100 ppm of NaCl = 100 mg NaCl/1 L = 67,87 ppm (67,87 mg/L) of Na
1 part per million (ppm) is the same as 1 mg/kg and mg/L 1 mg=0.0001 g 1 kg=1000 g 1 mg/ 1 kg = 0.0001/1000 = 1/1,000,000 and, 1% = 0.01 = 1/100 so, to get from 1% (1/100) to 1 mg/kg (1/1,000,000), you must multiply by 10,000 (invert) this means 1% = 10,000 ppm or mg/kg or mg/L
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
Parts per million (ppm) is the same as mg/L. So, dissolve 5 mg of NaOH in 1 L of water and viola!
5 mg of an element or compound in 1 L of solution
The amount of chemical to make 200 ppm depends on the final volume of the solution. If you had 1 liter, then it would take 200 mg of chemical (0.2 grams). If you had a lake or a pond, it would take a lot more, and you'd need to know the volume of the lake or the pond.
1 mg/L = 1 ppmAssumption: 1 cm3 of pure water = 1g =1000mg1 litre water = 1000 ml = 1000 g = 1 000 000 μl or 1 000 000 mg1 mg/1 litre = 1 mg/ 1 000 000 μl = 1mg/1 000 000 mg = 1 ppmNote:mg/L is most frequently used in measurements of material in water or other liquids. ppm is used as a measure of gases in other gases and is based on volume or mole ratios not weight or mass. As a clarification ppm is usually written as ppmv (parts per million volume)
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.
