- 0,9 g/L NaCl equal to 0,154 moles

- but because NaCl is dissociated in two ions in water the relation is 1 mol NaCl equal 2 osmol/L

- and so 0,9 % NaCl equal 308 milliosmole/L

What aprroximate osmolarity in ecf and icf?

The approximate osmolarity in the extracellular fluid (ECF) is around 290-310 mOsm/L, while the osmolarity in the intracellular fluid (ICF) is similar, ranging from 275-300 mOsm/L. The difference in osmolarity helps maintain proper cell volume and function.


What is the typical osmolarity of human blood?

300 mOsM/L


What is the osmolarity of the filtrate at the end of the proximal tubule?

Isotonic- 300 mOsm Per Pearson Yes, the osmolarity of the filtrate would be about 300 mOsm because both solutes and water are reabsorbed in the proximal tubule. As particles are reabsorbed, water follows osmotically.


What is the molarity of a 3000 liters solution containing 300 grams of NaCl?

Molarity = moles of solute/Liters of solution Find moles NaCl 300 grams NaCl (1 mole NaCl/58.44 grams) = 5.13347 moles NaCl Molarity = 5.13347 moles NaCl/3000 Liters = 1.71 X 10^-3 M sodium chloride ----------------------------------------


Is 0.3 NaCl an isotonic solution?

A solution is only isotonic compared to another solution. The statement that .9 NaCl is isotonic is incomplete. You are referring to the fact that it is isotonic with blood serum. This means they have the same osmotic pressure as each other which controls how they pass through the semi permeable membrane of blood vessels. .9 NaCl is isotonic with blood serum and that means that it will diffuse out of the blood vessel after IV injection in a similar fashion to the components of the blood serum itself. .9Nacl contains about 154 mOsm/L of Na and 154 mOsm/L of Cl giving the solution an osmolarity of 308 mOsm/L. The osmolarity of blood is about 300-310 mOsm/L so the two are very close and that's why .9NaCl is considered isotonic for IV solution.


How to calculate the percentage of NaCl to M and mOsm?

9 g/L NaCl = 0,9 g/100 mL = 0,154 moles/L = 300 mOsm/L


How many grams of sodium chloride is in 0.40 moles?

Molarity = moles of solute/Liters of solution ( 300 ml = 0.300 Liters ) For our purposes, Moles of solute = Liters of solution * Molarity Moles NaCl = 0.300 Liters * 0.15 M = 0.05 moles NaCl =============


Why does one feel thirstier after she or he drink soft-drinks?

Being thirsty is a brain response due to increased blood osmolarity or decreased blood volume. The human body must keep its blood osmolarity close to 300 mOsms in order to function properly. If it is increased or the blood volume is decreased the brain will release hormones such as ADH(antidiuretic hormone- to save water) and will trigger a thirst response in the brain. Soft-drinks as opposed to water, have an increased osmolarity and therefore cannot lower your blood osmolarity to the same degree as water and therefore do not relieve your thirst. Hope that helps


How much salt percentage in human body?

3.4% which is the same as the percentage of salt in the ocean


Where is osmolarity greatest in kidney?

Osmolarity is greatest in the innermost portion of the medulla near the renal pelvis due to the osmotic gradient. As one goes deeper into the renal medulla, the osmotic gradient increase. The osmolarity varies from 300 mOsm at the edge of the medulla to the innermost at approximately 1200-1400 mOsm. Think of the movie, Silence of the Lamb, when Anthony Hopkins eats that kidney, as he eat closer and closer to the kidney, it get salter. The medullary osmotic gradient is used for water reabsorption in the collecting duct, when ADH is present, thus increasing blood volume and result in increasing blood pressure.


Is 0.225 percent sodium chloride hypertonic or hypotonic?

0.9% sodium chloride is isotonic, thus 0.45 and 0.225 % sodium chloride solutions are hypotonic. osmolarity of 0.9% is 308 mOsm/L and 0.45 is 154 and 0.225 is 77 mOsm/L and body fluids have an osmolarity 250-300 mOsm/L.


How much is 300 crore rupes in pounds?

To convert 300 crore rupees to pounds, you need the current exchange rate. As of my last available data, 1 crore is 10 million, so 300 crore is 3 billion rupees. If we assume an exchange rate of approximately 0.011 pounds per rupee, then 300 crore rupees would be about £33 million. Please check the latest exchange rates for precise calculations.
