yes it is isotonic solution.
No because 4.5 is greater than .045 which is the same as 0.045
No.

Multiply it by 100 and then it becomes 4.5%
it is 1/5 saline
no

Yes this saline is a hypertonic solution but 3% saline is also not normal. There is nothing "normal" about it. There is only one "normal saline" and that is 0.9%.
Sodium chloride 0.9 percent and normal saline are not quite the same solution. While they share the same osmolality, sodium chloride contains more salt.
How do we prepare a normal saline?

percent of 0.045 = 4.5%
Normal Saline is an isotonic solution.
Normal Saline 0.9% is called an isotonic solution. A 0.0% saline solution is called a hypotonic solution. A solution of this concentration would cause water to diffuse into the red blood cells and cause them to burst open. A 10% saline solution is called a hypertonic solution. A solution of this concentration would cause water to diffuse out of the red blood cells, making them shrivel up and shrink.
