The concentration of calcium ion in blood is found to be 1.21 mmol/L. What is this concentration in mEq/L?

concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L

Explanation:

given

concentration of calcium ion in blood = 1.21 mmol/L Concentration in mEq/L = Concentration in mmol/L x valence of the ion but Valence of Ca2+=2 The valence electron is the number of electron present in the outermost shell. Calcium belongs to the group2 elements also known as the alkaline earth metal, and their valence electron is 2.

Hence, concentration of calcium ion mEq/L = 1.21 x 2 = 2.42mEq/L

where mEq/L = milliequivalent per liter
