mg = (mEq • atomic, molecular or formula weight) / valence
Atomic weight of potassium [K] is 39.0983
Atomic weight of chlorine [Cl] is 35.453
The molecular weight of potassium chloride [KCl] is sum of the atomic weights above: 74.551 (rounded)
The valence of potassium chloride is 1
Thus:
(20mEq potassium chloride • 74.551) / 1 = 1491.0 mg potassium chloride
Which breaks down to 781.960 mg of elemental potassium [K], and 709.060 mg of elemental chlorine [Cl].

Numerical answers to this question are all nonsense. A number would depend on the element, molecule or formula in question, and none was specified. The correct answer to this question (as posed) is:
mg = (mEq • atomic, molecular or formula weight) / valence
The first answer above is correct for hydrogen; the second is about right for potassium chloride. For a more detailed answer for potassium chloride, see the related question.

ANSWER: 1500 mg.
To convert milliequivalents (mEq) of an electrolyte to milligrams, you need to know the atomic weight of the element. For example, for sodium (Na), 1 mEq is approximately 23 mg. So, if you have 40 mEq of sodium, it would be around 920 mg.
The answer is 0,0584 g or 58, 4 mg.
mEq. or milliequivalents is one thousandth of a chemical equivalent. It is calculated by multiplying the milligrams per liter by the valence of the chemical and dividing by the molecular weight of the substance.
To convert milliequivalents (mEq) of potassium citrate to milligrams (mg), you need to know the molar mass of potassium citrate. If we assume potassium citrate has a molar mass of approximately 306 g/mol, then 40 mEq of potassium citrate would be equivalent to about 12.2 grams or 12,200 milligrams.
The atomic weight of potassium is 39.1 g/mol. To convert milliequivalents to milligrams, you would multiply the milliequivalents by the equivalent weight of potassium. Therefore, to find the number of milligrams in 20 milliequivalents of potassium, you would multiply 20 milliequivalents by the equivalent weight of potassium in milligrams, which is 39.1 mg/meq.
There are approximately 2.53 milliequivalents (mEq) in 99 milligrams of potassium.
Potassium has a gram atomic mass of 39.1, to three significant digits (one more significant digit than "20 meq" has). Therefore, one meq = 39.1 mg, and 20 meq = 20(39.1) = 7.8 X 102 mg, to the justified number of significant digits.
To convert 100 milliequivalents (mEq) of sodium to milligrams (mg), you can use the conversion factor for sodium which is 1 mEq = 23 mg. Therefore, 100 mEq of sodium is equal to 2300 mg.
To convert milliequivalents (mEq) of Potassium to grams, you need to know the molar mass of Potassium, which is approximately 39.1 g/mol. Since 1 mEq is equivalent to 39.1 mg of Potassium, you can convert 20 mEq to grams using this ratio, which is equal to 0.78 grams.
To convert milliequivalents (mEq) of sodium to milligrams (mg), you need to know the atomic weight of sodium. The atomic weight of sodium is approximately 23 g/mol. So, to convert 45 mEq of sodium to mg, you would multiply 45 mEq by the atomic weight (23 g/mol) to get 1035 mg.
there are 1,000 milligrams in every gram so in 20 grams there are 20,000 milligrams.
