Normal saline is 0.9% weight/volume sodium chloride to water. This is 9 grams per litre.
NaCl has a molecular weight of 58.5, sodium (Na) has a weight of 23, which is 39.3% of the molecular weight. So sodium is 39.3% of the weight.
1 litre of saline has 9 grams, 250ml is a quarter of a litre, so has 9/4 grams = 2.25 grams.
39.3% of 2.25 g is 0.884 grams of sodium.

How much sodium chloride must be added to one liter of water to make normal saline?
To make normal saline, you would need to add 9 grams of sodium chloride to one liter of water. This is equivalent to approximately 0.9% saline solution.
How much of a 30 percent sodium chloride stock solution is needed to make 10 ml of a normal saline solution?
The volume is 0,3 mL.
Normal Saline what is the classification?
Normal saline is classified as an isotonic solution, meaning that it has a similar concentration of salts and water as the human body. It is used to restore fluid balance, treat dehydration, and dilute medications for injection.
How much saline to be added in gentamycin?
The recommended dilution for gentamicin is typically 0.9% sodium chloride (normal saline), with the amount depending on the specific concentration of the gentamicin solution being used. It is important to follow the instructions provided by the manufacturer or your healthcare provider to ensure the correct dilution is made.
What is the composition of physiological saline?
Physiological saline, also known as saline solution, is typically composed of 0.9% sodium chloride (NaCl) dissolved in water. This concentration closely matches the salt concentration found in human blood and is commonly used in medical settings for hydration, irrigation, and certain medical procedures.
