You cannot.
A millilitre is a measure of volume while parts per million is a measure of concentration. Except in the trivial case of pure hydrogen, the latter measure requires the concentration of hydrogen to be measured in the context of its mixture with other substances. No such substances have been mentioned.
500 ppm
1 GPG = 17.1 PPM
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
ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.ppm means 1/1,000,000; percent means 1/100. Therefore, every percent is equal to 10,000 ppm. To convert from ppm to percent, you divide by 10,000.
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.
The two terms ppm and ml are not similar measures. PPM (parts per million) is a ratio and can apply to mass, volume, etc., while ml (milliliter) is a unit of volume - 1/1000 of a liter.
if it is water 1000 ppm = 1 mg/ml
100 µl Benzone Triazole in 100 ml Methanol equals 1 ppm
As there are 1000 ml in 1 litre, multiply by 1/1000 or 0.001 to convert ml to l.
Assuming "ppm" is "ppmv" (1000 * 29 *.158 / 1000000 [1/ppm]) * 1000 [ml/l] = 4.58 ml ... if it is "ppmw", then it would be about 2.8 ml.
1 ml = 1 cm3
Multiply by 1 .
