Normal saline (NSS, NS or N/S) is the commonly used phrase for a solution of 0.90% w/v of NaCl, 308 mOsm /L or 9.0 g per liter.Less commonly, this solution is referred to as physiological saline or isotonic saline, neither of which is technically accurate.ince normal saline contains 9 grams of NaCl, the concentration is 9 grams per liter divided by 58.5 grams per mole, or 0.154 mole per liter. Since NaCl dissociates into two ions â sodium and chloride â 1 molar NaCl is 2 osmolar. Thus, NS contains 154 mEq /L of Na + and Cl â .
