An intravenous replacement solution contains 4.0 mEq/L of Ca²⁺ ions. How many grams of Ca²⁺ are in 3.0 L of the solution? A)0.24 g B)0.80 g C)0.40 g D)240 g E)4.0 g

Question

Quizplus · Accepted Answer

To find the grams of Ca²⁺ in 3.0 L, first calculate the total mEq: 4.0 mEq/L × 3.0 L = 12.0 mEq. Since 1 mEq of Ca²⁺ is equivalent to 20.04 mg, 12.0 mEq × 20.04 mg/mEq = 240.48 mg, which is 0.24 g.
