Milli equivalents and milli moles are units used to describe molecular or ionic grades of concentration. A milli equivalent or mEq is derived by dividing the concentration in millimol or mmol by the valency of the ion involved.
Eg: 1 mEq of sodium Na+ = 1 mmol of sodium (because valency is 1)
whereas 1 mEq of Ca2+ = .5 mmol of calcium. (because valency is
1potassium meq=? mmol/l
what is the difference between 10 meq er of potassium and 99 mg of potassium
xx mmol x 1 mole/1000 mmol x 58.5 g/mole
The question needs more detail. mmol is a measure of concentration and ml is a volume. Your question asks literally "If I place 1 mmol of a substance in a litre of water how many ml is this? I don't think you ment that.
4.98mmol
66 milliequivalent would be written as 66 mEq's.
1 mMol of k3po4 = 6 mEq as phospate
E.W= Molecular weight / # of ions = 100.09 (mg/mmol) /2 (meq/mmol) =50.043 mg/meq
1 mmol of Kphos = 1.46 KCL
yes
it depends on what you are measuring. Meq is a measure of charge. If you are measuring H+ which has one positive charge, 1 mmol = 1 meq for Ca2+, 1 mmol = 2 meq so the conversion will depend on the charge of the ion or molecule
what is the difference between 10 meq er of potassium and 99 mg of potassium
1 mEq=1 mmol/valence e.g.For sodium, 1 mEq=1mmol/1 (valence of sodium=1) means, 1 mmol sodium=1 mEq of sodium take for calcium,valence=2 1 1 mEq of calcium=1mmol/2=0.5 mmol of calcium
Since potassium has a valence of one, its equivalent weight is the same as its molecular weight; therefore, 2.9.
The answer is 2.53 mEq.Here is my work:99mg Potassium x (1mmol/39.0983mg potassium) x (1mEq/1mmol) = 2.53 mEq* The 39.0983 comes from the atomic mass of Potassium which means that 39.0983 grams = 1 mol (which also means 39.0983 milligrams = 1 millimol (mmol). 1 mmol of potassium = 1 milliequivalent (mEq) because milliequivalents are just the number of mmols of charges (positive/negative), and since potassium has 1 positive charge 1 mmol = 1 mEq.This is the over-the-counter dose. Most prescriptions are for 20mEq doses but usually range from 8mEq to 40mEq.
The question is vauge. Moles in atomic scale are equilivant to the number of electrons in the vallance of the magnesium atom ( the outer ring of electrons). Usually supplements are measured in milligrams or sometimes in international units (iu). What are you trying to find?
Every lab determines it own exact range. It is usually somewhere around 3.5 to 5 mEq (or mMol) per liter.
If a base is neutralizing an acid, it will require same no. of miliequivalents as that of acid.You can calculate them by using the equation below:-Meq. of acid= meq. of basenormality of acid x volume of acid =normality of base x volume of base(molarity x n-factor x volume)acid = (molarity x n-factor x volume)baseAdded:1 Meq. base can neutralise (by definition) exactly 1 Mmol H+ or 1 Meq of any acid.
