Some medical tests report results in milliequivalents per liter (mEq/L). An equivalent is the amount of a substance that will react with a certain number of hydrogen ions. A milliequivalent is one-thousandth of an equivalent. A liter measures fluid volume.
Is mEq L same as mmol L?
The abbreviation for mEq/L and mmol/L is milliequivalents per liter and millimole per liter respectively. 1 mEq/L is 1 times smaller than a mmol/L.
How many mEq are in a liter?
The equation to get mEq is therefore [(30 mg)(2)]/(58.44 mg/mmol) = 1.027 mEq. Since there are 400 mL = 0.4 L, the concentration in mEq/L is therefore 1.027/0.4 = 2.567 mEq/L.
How do you convert mEq L to mg L?
For example: Chloride – Its atomic mass is 35.4527 amu and its charge is negative (-1) which means its valence is 1. If your chloride concentration is 60 mg Cl/L, the mEq/L would be (60 mg/L) / (35.4527) = 1.6949152542372883 or 1.6949 mEq/L.
What is a Milliequivalent equal to?
A milliequivalent is equal to the number of univalent counter ions (H+ or OH) which will be needed to react with one molecule of the substance. When an atom has a valence of one ( e.g. Na+, K+, CI, etc.) a mEq of that ion is equal to the atomic weight of the atom in milligrams.
What does ML mean in medical terms?
Listen to pronunciation. A measure of volume in the metric system. One thousand mLs equal one liter. Also called cc, cubic centimeter, and milliliter.
How do you convert millimoles to Milliequivalent?
Example 1:
mg to mEq: Convert 750 mg of KCl (MW = 74.5 mg/mmol, valence = 1) to mEq = 10.07 mEq.mg to mEq: Convert 30 mg of calcium (Ca++) (atomic weight = 40.08 mg/mmol, valence = 2) to mEq = 1.5 mEq.mg to mmol: Convert 100 mg of phosphorus (P) (atomic weight = 31 mg/mmol) to mmol = 3.23 mmol.
How do you calculate mEq?
The expression mEq represents the amount of solute in mg equal to 1/1000 th gram of the equivalent weight of the substance. Equivalent weight = 147/2 = 73.5 grams and 73.5 grams/1000 = 0.0735 grams or 73.5 mgs.
How many mg is 10 mEq of potassium?
potassium citrate ER 10 mEq (1,080 mg) tablet,extended release.
How many mg is equal to 1 mEq?
Thus, 1 mEq is represented by 1 mg of hydrogen (1 mole) or 23 mg of Na+, 39 mg of K+, etc.
How do you convert mEq L to mg/l calcium?
Calcium has a molecular weight of 40.08 grams/mole Calcium has a valence of +2 The equivalent weight = (40.08grams/mole)/(2 equivalents/mole) = 20.04 grams/eq To convert to mg/meq you simply multiply g/eq by 1000 mg/g and divide by 1000 meq/eq, thus g/eq = mg/meq If your sample contains 30 mg Ca/L, what is the …
Is mg/l equal to ppm?
No, mg/L is not always equivalent to ppm. Whereas ppm is a volume-to-volume or mass-to-mass ratio, mg/l is a mass-to-volume relationship.
Is mEq L the same as mOsm L?
The mEq/L is the ion concentration, in millimoles, multiplied by the number of electrical charges on the ion. The milliequivalent unit incorporates both the ion concentration and the charge on the ions. Thus, for ions that have a charge of one, such as sodium (Na+), one milliequivalent is equal to one millimole.
How do you convert mEq L to PPM?
1 meq/L = 2.8 dKH = 50 ppm CaCO3 equivalents. So just multiply your reading that is in meq/L by 50 to get ppm.
