2.2 lbs. 1 liter of pure water weighs 2.2 lbs. The NaCl content (approximately 9 grams) dissolved is negligible here as it displaces water and so we can state that 1 liter saline weighs approximately 2.2 lbs as well.

The answer is 9 g NaCl.
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.
The weight of saline solution depends on how much mass it has. An example of weight is as follows: a C cup saline breast implant weighs 2.2 pounds or 35 ounces.

It depends on what the liter contains.
kg is a measure of weight; liter is a measure of volume
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.
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.
A liter is a unit of volume not weight, therefore to determine how much a liter weighs it depends on what you're measuring. A liter of water has a different weight than a liter of sand and so on.
