How do you calculate Milliequivalents?

How do you calculate Milliequivalents?

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.

What is a mEq equal to?

Some medical tests report results in milliequivalents per litre (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 litre measures fluid volume. It is a little bigger than a quart.

How do you calculate KCl mEq?

Step 3: 1 mEq KCl = 1/1000 x 74.5 g = 0.0745 g = 74.5 mg Step 4: 1 mEq KCl = 74.5 mg; 1.5 g KCl = 1500 mg; How many mEq in 1500 mg?

Is mEq L same as mmol L?

“Meq” is a unit of measurement that is referred to as one-thousandth of an equivalent of a chemical. Meq is used to measure substances with electrolytes. “Mmol,” on the other hand, is a unit of measurement that is referred to as one-thousandth of a gram molecule.

How do you find net Milliequivalents?

When an atom has a valence of two or more (e.g. Mg+2, Ca+2, Al+3) a mEq of that ion is equal to the atomic weight of the atom in milligrams divided by the atom’s valence. For example, one mEq of calcium (Ca+2) with an atomic weight of 40 weight 20 mg.

How do you calculate milliequivalents of base?

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.

What does 20 mEq stand for?

The Potassium Chloride Extended Release Tablets USP, 20 mEq product is an immediately dispersing extended release oral dosage form of potassium chloride containing 1500 mg of microencapsulated potassium chloride, USP equivalent to 20 mEq of potassium in a tablet.

What is Milliequivalent in chemistry?

Milliequivalents (mEq) 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.

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.

How do you convert Milliequivalents to millimoles?

Thus, for ions that have a charge of one, one milliequivalent is equal to one millimole. For ions that have a charge of two (like calcium), one milliequivalent is equal to 0.5 millimoles.

How do you convert millimoles to Milliequivalents?

Example 1:

1. mg to mEq: Convert 750 mg of KCl (MW = 74.5 mg/mmol, valence = 1) to mEq = 10.07 mEq.
2. mg to mEq: Convert 30 mg of calcium (Ca++) (atomic weight = 40.08 mg/mmol, valence = 2) to mEq = 1.5 mEq.
3. mg to mmol: Convert 100 mg of phosphorus (P) (atomic weight = 31 mg/mmol) to mmol = 3.23 mmol.

What is 1 mEq/L in mmol/L lithium?

Formula to convert mEq/L values to mmol/L Lithium , is 1 mEq/L is equivalent to 1.0 mmol/L . To calculate just use formula 1.0 mEq/L * mmol/L.

How do you calculate milliequivalents in chemistry?

Sciencing Video Vault. In contrast to an equivalent, which is a quantity, molarity (M) is concentration, describing the number of moles per liter of a substance in a solution. One formula for determining milliequivalents is: mEq = (mg × valence) ÷ molar mass. The information about valence and molar mass is in the periodic table of the elements.

How do you convert mEq/L to mmol/L?

Lithium mEq/L values to mmol/L converter. Formula to convert mEq/L values to mmol/L Lithium , is 1 mEq/L is equivalent to 1.0 mmol/L . To calculate just use formula 1.0 mEq/L * mmol/L.

What is the range of the lablab test for lithium?

Lab Test: Lithium Level 1 Therapeutic range: 0.6 mEq/L – 1.2 mEq/L (0.6 mmol/L – 1.2 mmol/L) 2 Toxicity: >; 1.5 mEq/L 3 Concerning Risk for Toxicity: >; 2.5 mEq/L (2 mmol/L)
