Question

A solution contains 43 meq/l of Cl⁻ and 11 meq/l of HPO₄²⁻. What is the concentration of Cl⁻ in mmol/L?

Answer 1

The concentration of Cl⁻ in mmol/L is the same as its concentration in meq/L because Cl⁻ has a single negative charge. Therefore, the concentration is 43 mmol/L.

Step-by-step explanation:

To determine the concentration of Cl⁻ in mmol/L, you can use the fact that the unit milliequivalents per liter (meq/L) is a measure of the amount of a substance in a solution based on the charge of the ions.

Since Cl⁻ has a charge of -1, the milliequivalents for Cl⁻ directly translate to millimoles. Therefore, a concentration of 43 meq/L of Cl⁻ is equivalent to 43 mmol/L of Cl⁻.
