An oral rehydration solution contains 30 mEq/L of citrate^3-, what is the molarity of citrate in this solution? A)0.09 M B)90 M C)10 M. D)0.01 M

Question

Quizplus · Accepted Answer

To calculate the molarity of citrate, we need to know the molar mass of citrate. Assuming that the given concentration of citrate is referring to the mEq/L of citrate molecules, we can calculate the molarity of citrate by dividing the molarity of the charge (30 mEq/L) by the absolute value of the charge of citrate (-3):

molarity = (30 mEq/L) / 3 = 10 mM = 0.01 M

Therefore, the correct answer choice is D.
