There is no simple relationship.
Weight in mg is a measure of mass (times gravity).
"ppm" (parts per million) is a measure of strength of mixture (or solution/emulsion, etc).
For this, you need to know the masses of the main body and of the "pollutant";
and then do some arithmetic.
One can convert mg to kg by dividing milligrams by 1000.
Multiply ppm by 10000.
1 mg/kg = 1 ppm 1 mg = 1000 micrograms (ug) so 10 ug/kg = 0.01 mg/kg = 0.01 ppm
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)
Does not convert; milligrams (mg) and grams are measures of weight or mass and mL (milliliters) is a measure of volume.
You can not convert mg (weight) to volume (ml).
5000 mg = 5 ppm
One can convert mg to kg by dividing milligrams by 1000.
To convert ppm mass basis to ppm volume basis: ppmm/molecular weight x 22.4 = ppmv
10 ppm mole multiply by molecular weight of water then divided by sample density
You cant...Coz its not a ratio...You can find number of moles, weight, and etc but not ppm bcoz ppm is termed from composition
Write an equation representing the ppm concentration: ppm = mass solute (mg) ÷ volume solution (L) Extract the data from the question: mass solute (NaCl) = 0.0045 g. ... Convert the mass in grams to a mass in milligrams: mass NaCl = 0.0045 g = 0.0045 g × 1000 mg/g = 4.5 mg.
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
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
No 100 ppm of NaCl = 100 mg NaCl/1 L = 67,87 ppm (67,87 mg/L) of Na
Does not convert; milligrams (mg) and grams (g) are measures of weight or mass and mL (milliliters) is a measure of volume.
Answer will be (mg/L) as CaCO3 units of ppm are the same as mg/L. Hardness = 2.5(mg Ca/L) + 4.1(mg Mg/L) In this case: 2.5x78.4 + 4.1x104.5 = 624.45 mg/L
