Calculate the percent saline (NaCl) solution that would be isotonic. The molecular weight of NaCl is 58.44 g/mol. Show your calculations. (Hint #1: start with normal cell and plasma osmolality, which is 0.3 Om/kg and convert that to percent saline. Hint #2: NaCl is ionic, so it dissociates in water).
