Question

"the osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant r . suppose the osmotic pressure of a certain solution is measured to be 23.atm at an absolute temperature of 309.k"

Answer 1

Answer: -

The concentration is 0.91 mol/ L

Explanation: -

The osmotic pressure = 23 atm

Absolute temperature = 309 K

Universal gas constant = 0.08206 L atm mol⁻¹ K⁻¹

We know the formula

Osmotic pressure = molar concentration x universal gas constant x absolute temperature

Plugging in the values

23 atm = molar concentration x 0.08206 L atm mol⁻¹ K⁻¹ x 309 K

Molar concentration = $\frac{23}{0.08206 x 309}$ mol/ L

                                  = 0.91 mol / L

Answer 2

The concentration is 0.91 mol/ L

Further Explanation:

Solution:

The osmotic pressure = 23 atm  

Absolute temperature = 309 K

Universal gas constant = 0.08206 L atm mol⁻¹ K⁻¹

Formula is:

Osmotic pressure = molar concentration x universal gas constant x absolute temperature

23 atm = molar concentration x 0.08206 L atm mol⁻¹ K⁻¹ x 309 K

Molar concentration= 0.91 mol / L

Osmotic pressure:

Osmotic weight is the base weight which should be connected to an answer for avert the internal progression of its unadulterated dissolvable over a semipermeable layer. It is additionally characterized as the proportion of the propensity of an answer for take in unadulterated dissolvable as a natural side effect.  

A case of osmotic weight:  

An incredible case of a semipermeable layer is that inside the shell of an egg. After shell evacuation is cultivated with acidic corrosive, the film around the egg can be utilized to show assimilation. Karo syrup is basically unadulterated sugar, with almost no water in it, so its osmotic weight is low.  

osmotic weight in basic terms:  

Osmotic weight is the power brought about by an answer going through a semi porous surface without really trying, which is equivalent to the power required to oppose the arrangement from going back through the surface. A case of osmotic weight is the procedure to channel water.
