What is the concentration in mg/mL of a solution containing 2 mEq of potassium chloride?
39.9 mL
Note- The molar mass of potassium chloride (KCl) is Mm=74.55 g/mol M m = 74.55 g/mol . Thus, the volume of the solution containing 2 mEq of potassium chloride is 39.9 mL.
How to calculate potassium mEq?
1. How many mEq of potassium are there in 750 mL of solution that has a K+ concentration of 58.65 mg/L? (Note: The molar mass of potassium, given in the periodic table, is 39.1 g/mol.) From the above equation, and with the valence of elemental potassium being 1, you have mEq = [(58.65 mg)(1)]/39.1 mg/mmol = 1.5 mEq.
How many Milliequivalents are in a milliliter?
Cross Multiply: 40 mEq * Xml = 10 mEq * 200 ml. Now calculate the drip rate for the infusion….Medication Calculation.

How many mg is 8 mEq of potassium?
8 mEq (600 mg) and 10 mEq (750 mg)
How do you convert mg of potassium to mEq?
- To convert milligrams to milliequivalents use the formula: mEq = (mg x valence) / atomic or molecular weight.
- One thousand milliequivalents equals one equivalent.
How many mg is 10 mEq of potassium?
How many mg of potassium are in mEq?

How many milligrams are in a mEq?
To convert milligrams to milliequivalents use the formula: mEq = (mg x valence) / atomic or molecular weight. One thousand milliequivalents equals one equivalent.
What is milli equivalent?
Medical Definition of milliequivalent : one thousandth of an equivalent of a chemical element, radical, or compound —abbreviation mEq.

How many mg is 2 mEq of potassium?
Each mL of Potassium chloride for Injection Concentrate contains 2 mEq of K+ and CL-equivalent to 149 mg of potassium chloride and has an osmalarity of 4000 mOsmol/L (calc).
How do you calculate mEq from mg/mmol?
First, you need the total mass of potassium in this solution, which is obtained by multiplying the concentration in mg/L by the volume of solution in liters: (78.2 mg/L)(0.75 L) = 58.65 mg From the above equation, and with the valence of elemental potassium being 1, you have mEq = [(58.65 mg)(1)]/39.1 mg/mmol = 1.5 mEq.
What is the difference between molarity and Meq?
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.
How do you calculate concentration from molarity?
Solution: Concentration = Molarity x Molecular Weight. = 5 x 7. = 35 mg/ml.
What is the unit of concentration in mg/mL?
mg/ml. In chemistry, the concentrations are usually expressed in the units of milligrams per milliliters(mg/ml). But for the purpose of quality assurance, the data’s are expressed in molarity (Moles per litre, M).
