Answer 1

Answer #1

The given details:

The concentration of Mg²⁺ = 120 mmol/L

Valency of Mg = 2

mEq/L of an Mg²⁺ =?

The calculation for finding mEq/L of an Mg²⁺

mEq = [mass of substance (in milligram) * valence] / molar mass

The number of mEq = millimoles * valence

mEq/L of a Mg²⁺ = 120 * 2

The number of mEq/L of an Mg²⁺ = 140 mEq/L
