mg to mEq formula
To convert milligrams (mg) to milliequivalents (mEq), you can use the following formula:
mEq = (mg * V) / At Wt
Where,
- mg = milligrams
- mEq = milliequivalent
- At Wt = Atomic Weight or molecular weight
- V= Valance number
How to convert mg to mEq?
To convert milligrams (mg) to milliequivalents (mEq), you need to know the Atomic weight and valence of the substance
Here’s a step-by-step guide:
- Select the substance : (eg – Na)
- Determine the mg
- Next, look up the atomic weight of the substance (use the periodic table)
- Next, Determine the valence (ex – valence of magnesium is 2)
- Next, use the above formula
Solved Example
Example – 100mg of sodium (Na). Sodium has a valence of 1 and an atomic weight of 23. To convert it to mEq (milliequivalent).
solved –
- milligrams = 100 mg
- atomic weight of sodium = 22.99 g/mol
- Number of valence = 1
Put all values into the formula
mEq = (100mg * 1) / 22.99 = 4.3497 mEq
mEq ≈ 4.3497 mEq
100mg of sodium is equivalent to approximately 4.3497 mEq.
