To convert millimoles per liter (mM) to parts per million (ppm) for a given substance, you would need to know the molecular weight of the substance. Then, you can use the formula: ppm = (mM) x (molecular weight of the substance) / 1. So, multiply the concentration in mM by the molecular weight and this will give you the concentration in parts per million.
M is moles per litre, ppm is parts per million, or mg/litre
so take molarity as no. of moles. use the gram molecular weight.
use formula no. moles = mass/gmm. that finds the mass in grams. multiply by 1000 to convert to milligrams, or ppm.
eg1M HCl. GMM HCl is 1+35.5=36.5
no moles = 1.
Moles x gmm = grams
36.5 x 1 = 36.5 g / litre.
x 1000 = 36500ppm
To convert mM to ppm, multiply the concentration in mM by the molecular weight of the solute. For 1mM CaCl2, it works out to 110.9ppm. The expanded math is below:
1mM CaCl2 = 0.001mol/L
Formula wt = 110.9 g/mol
0.001mol/L x 110.9g/mol = 0.1109g = 110.9mg
Since mg/L = ppm,
110.9mg/L = 110.9ppm
Hope this helps.
ppm is usually a molar ratio: 1 mole substance per 1x106 moles of total solution.
mg/L (milligrams/liter) is more often used for liquid solutions
pH is related to the molar concentration of the H+ ion in a solution in moles/liter. The pH value is the negative logarithm of the moles H+ concentration in a liter of the solution.
So we have several interacting concentration, volume and mass measures in play.
Let's assume a pH of 5 as our test case.
This means there are 1x10-5 moles of H+ in one liter of the solution. At this low concentration the mass of the solution will not be much different fom water, so the solution has mass of 1000 grams or 1,000,000 milligrams.
H+ has a molar mass of 1 gram/mole or 0.00001 gram per 10-5 mole.
So a weight ppm value of the H+ ion in the solution is 10-5 g/liter (or 1 million milligrams). Converting g to mg we arrive at the answer that a pH contains 10-2 ppmw of H+.
However if the ppm is to indicate the ppm value of the acid contributing the H+ ions it is necessary to change the molar mass of H+ to the molar mass of the acid (you have to know what acid is present).
Using H2SO4 as an example, the molar mass is 98 g/mole and each mole
contributes 2 moles of H+ to the solution. There would be (98/2)x 10-5 ppmw (or (49x 10-5 ppmw)of H2SO4 in the solution.
You don't. They have to do with different types of measurements.
Divide by 10,000. Ppm is an abbreviation for parts per million, so
X parts/million * million/10,000 hundred = (X/10,000) parts/hundred = (X/10,000)%.
You must know the molecular weight to perform this calculation; parts per million is almost always measured in terms of mass/weight, not mole fraction.

How do I convert a .06 percent selenium to 90ppm?
To convert 0.06% selenium to ppm, you need to multiply by 10,000. Therefore, 0.06% selenium is equivalent to 600 ppm. To convert 600 ppm to 90 ppm, you would need to dilute the solution by a factor of 6.67 (600 ppm / 90 ppm).
How do you convert 0.5 percent to ppm?
To convert 0.5 percent to parts per million (ppm), you multiply by 10,000. So, 0.5 percent is equal to 5,000 ppm.
What is 28 ppb equal to in ppm?
To convert parts per billion (ppb) to parts per million (ppm), you divide by 1000. So, 28 ppb is equal to 0.028 ppm.
How do you convert ppm into gpg?
To convert parts per million (ppm) of a substance to grains per gallon (gpg), you need to know the atomic or molecular weight of the substance. Once you have this information, you can use the formula: gpg = ppm x (atomic/molecular weight/7000).
How covert ppm to pH?
In order to convert ppm to pH, one must first understand that 1 ppm is equivalent to 1mg/L. For example, if one wanted to convert 20mg/L into a pH one would use the equation 0.02g/36.45g/mole which is equal to a pH of 3.2.
How I can transform 4 mm NaCl to ppm?
mm is unit of length, ppm is a non-SI unit of concentration.
How do you convert 0.5mM to ppm?
0.5Mm = 50 PPM
How do you convert to ppm to percentage?
Multiply ppm by 10000.
Convert 322.000 ppm to percent?
322 ppm = 0.0322%
How do you covert from 5 ppm to percent?
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.
