How many ml of 23.4% NaCl would you need?

You need 51.3 mEq of NaCl to make 1/3 NS 1 liter bag.

How many ml of 23.4% NaCl would you need? (Molecular weight of Na is 23 and Cl is 35.5)
A . 12.82ml
B . 16.82ml
C . 23.4ml
D . 58.5ml
E . 10ml

Answer: A

Explanation:

1mEq NaCl= 58.5; Valence = 1. mg = mEq × molecular weight / valence. mg = 51.3mEq × 58.5mg / 1 = 3001.05mg = 3g. 23.4 g/100ml = 3g/Xml X = 12.825mL
