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.
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.
The volume is 0,3 mL.
i just want to know the classification of normal saline?It is just a 0.9% solution of table salt (sodium chloride) dissolved in water. By comparison, ocean water is about 3.5% which is much saltier.
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.
A physiological saline is a solution of salts and sugars intended to act as a medium for growing or maintaining live tissue. The solution mimics the salt concentrations of the tissues' natural environment, while providing some buffering to maintain the pH of the solution. Since different tissues from different species are subject to varying internal environments, a large number of physiological salines have been developed over the last century. For example, the original Ringer's solution was developed to mimic amphibian blood, Hank's solution was intended for human tissue, Cortland's saline was designed for the tissue of freshwater fishes, and phosphate-buffered saline is commonly used as a divalent-free saline that is isotonic with human blood. While the composition of every solution is unique, physiological salines developed for vertebrates (such as those mentioned above) have much in common. Such salines are predominately sodium chloride with a concentration of about 0.9% (or 9.0g/L). In lesser concentrations, they often include: sodium monobasic phosphate, sodium dibasic phosphate, sodium bicarbonate, potassium chloride, calcium chloride, magnessium chloride, magnessium sulfate, and glucose.
Normal saline solution has a sodium chloride concentration of 9 g/L.

A liter of normal saline, which is composed of water and salt, has a weight of approximately 1 kilogram or 1000 grams at room temperature.
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.
Assuming saline is 0.9% sodium chloride in water, the density is approximately 1.0046 g/ml. Therefore, 10 ml of saline would weigh around 10.046 grams.
1g of NaCl is about 17 mmol Na. thus, 15g of Na is about 255 mmol Na. 1 L of normal saline (0.9%) gives 154mmol Na. so, about 1.66L of normal saline gives about 255 mmnol Na. Edited by dejswa . . . 15 g of Na (molecular wt of ~23) is actually 652 mmol of Na. You were calculating the mmol of NaCl. This gives about 4.2 liters of normal saline. Or calculated another way, 0.91% (normal) saline is 9.1 gm of NaCl per liter. Na is ~40% of the wt of NaCl, thus 15 gm of Na represents 37.5 grams of NaCl. Divide by 9.1 and you get about the same answer. That would be quite a deficit of Na. You would have to sweat about 19 liters to lose that much Na, but an 8 hr mtn bike race in the Texas summer would do it.
at my hospital, it costs $50. that's right, fifty dollars!
The weight of saline solution depends on its volume and concentration. The density of saline solution is approximately 1.025 grams per milliliter, so a liter of saline solution would weigh about 1.025 kilograms. For smaller quantities, you can calculate the weight by multiplying the volume in milliliters by the density in grams per milliliter.
Saline soil is soil that has a high concentration of soluble salts, such as sodium chloride, which can hinder plant growth by altering the osmotic potential of the soil solution and causing toxicity to plants. Saline soils are common in arid and semi-arid regions where evaporation rates exceed precipitation rates, leading to the accumulation of salts in the soil. Agricultural practices, such as irrigation with saline water, can also contribute to soil salinity.
The average blood loss during menstruation is 35 milliliters with 10-80 milliliters considered normal.
