The atomic weight (in unified atomic mass units or daltons) is also the molar mass is grams per mole. You can get each element from the periodic table, which includes atomic weights, and for a molecule, add up the weights of all the atoms in the chemical formula.

Potassium is 39.0983 g/mol (39.10 is a good rounded value, or even 39, for many applications) Equivalence is based on the moles of electrons gained or lost in the ionized form from a mole of the substance. Since potassium has a valence of +1, moles and eqvs are identical. For something with a valence of +2 like calcium, one mole would be two eqv.

So 39.10 mg = 1 mmol = 1 mEq. The relationship is generally unique for each substance and has to be computed from atomic weights, and valence observed in chemical reactions.

convert 40meq to mg

Going by what was said above, 40 mEq must be equal to 40 mmol, as potassium has a valency of +1.

One mole of potassium would weigh 39.10 grams.

So 40 mmol would weigh 1.564 grams.

40 mEq = 40 mmol = 1.6 grams, rounding off.

please tell me how to convert 1mg of potassium to 8meq per day

Please advise how to convert 20 meq of Potassium to milligrams.

see post #2 or#4.

10 meq equal to how many mg

see pots 2 and 4.
391 mg

Your replies are confusing. You say potassium is 39.10g then in another sentence it is 39.10mg. That is a life threathening difference. The average lay person is depending on and using this info.
