Answer:
466mEq
Step-by-step explanation:
First, we need to know the concentration of NaCl in a normal saline solution, this is by definition 0.9%, meaning we have 0.9g of NaCl per 100ml of solution, we want to know how much NaCl we have in 3L (3000ml):
So, we have 27000mg in 3L of normal saline solution.
Now, acording to our milliequivalent (mEq) equation () where pE is de molecular mass of NaCl divided by their charges, in this case 1:
Finally we substitute in the mEq formula:
