1.   A 300 mOsM NaCl solution is (select one) isoosmolar, hypoosmolar or hyperosmolar to a RBC.

2. A 400 mOsM NaCl solution is (select one) isoosmolar, hypoosmolar or hyperosmolar to a RBC.

3. A 300 mOsM Urea solution is (select one) isotonic, hypotonic or hypertonic solution for a RBC.

Solution

1. These two solutions would be isoosmolar beaches red blood cells do have approximately the same osmolarity. That means RBC have an osmolarity of 300 Mosm/L.
