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].

This dangerously wrong. Check drugs.com.
20 MEQ is about 1500 mg.

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.
780 mg 1491.0 mg of potassium chloride (which contains 781.960 mg of elemental potassium)

I normally would type out the answer for this but I think you can find a better answer at the following web site drugs.com/ppa/potassium-products.html
ANSWER: 1500 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.
750 mg potassium chloride is equivalent to 10 mEq
No. You'd need about 4 tablets of 99 mg KCl to equal 10 mEq of prescription-strength KCl, 8 tablets to equal 20 mEq.
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.
There are 10 milligrams in one centigram. Therefore, 20 milligrams is equal to 20/10 = 2 centigrams.
there are 1,000 milligrams in every gram so in 20 grams there are 20,000 milligrams.
how many mg in 20 meg potassium
Per FDA factsheet ... Potassium chloride extended-release capsules, USP, 10 mEq is an oral dosage form of microencapsulated potassium chloride containing 750 mg of potassium chloride USP equivalent to 10 mEq of potassium.
You'll have to explain what a "meq" is.
0,028 mEq
