lease explain any calculation that needs to be done.
A red blood cell is placed in a saline (NaCI) solution, and the cell's volume increases to 1.5 times its
original volume. This finding indicates that the Na+ concentration in the saline solution is
approximately
a) 50 mEq/L
b) 75 mEq/L
c) 100 mEq/L
d) 200 mEq/L
