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
