Saline Solution

Post by deleted-58060 »

All the saline solutions I can find is 0.9% and I need saline solution that is 0.3%. How much water do I need to add to the solution to make it 0.3%?

GraceMorris - A salinity of 0.9% is considered 'normal saline' or NS in medical and lab context. It consists of about 0.9 mg of NaCl (salt) to 100 ml of solute, or pure water. To dilute your 0.9% solution to achieve a 0.3% solution add two parts of distilled water to one part of your 0.9% solution.
