Recall the molarity:
IV Saline solution → NaCl solution
Concentration of dissolved particles in blood = concentration of NaCl solution
[NaCl] = 0.30 M = 0.30 mol/L
The total concentration of dissolved particles in blood is 0.30 M. An intravenous (IV) solution must be isotonic with blood, which means it must have the same concentration.
(c) If the patient is given 150. mL/h of IV saline for 1.5 h, how many grams of NaCl did she receive?
