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

The question is incomplete,complete question is:

An intravenous replacement solution contains 4.0 mEq/L of ions. How many grams of

(Hint: 1 mole of ions = 2 mEq of

240.0 grams of are in 3.0 L of the solution.

Explanation:

Concentration of calcium ions = 4.0 mEq/L

Volume of the solution = 3.0 L

Millimole equivalents of calcium ions = 4.0 mEq/L × 3.0 L = 12.0 mEq

1 mole of ions = 2 mEq of

Moles of calcium ions in 12.0 mEq =

Mass of 6.0 moles of calcium = 6.0 mol × 40 g/mol = 240.0 g

240.0 grams of are in 3.0 L of the solution.
