Aringers solution for intravenous fluid replacement contains 155 meq of ca2+ per liter of solution. if a patient receives 1850 ml of ringer’s solution, how many moles of calcium ions were given?

Milliequivalent is a unit that made from millimol unit multiplied by the valence of the atoms. Calcium has 2 valence electron so the mEq would be twice as much as the mol. The solution has 155meq/liter and the volume is 1850ml. Then, the amount of calcium in the solution should be:

1850ml * (155mEq/1000ml) / (2mEq/mmol)= 143.375mmol= 0.144 mol
