Maybe because gravity has control of each formation of the solarsydtem thats why its just a guess

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant

enot [183]

Answer: $C=\frac{\pi}{R\times T}$

Explanation:-

Osmotic pressure is a colligative property which depends on the amount of solute added.

$\pi=CRT$

$\pi$ = osmotic pressure = 5.1 atm

C= concentration in Molarity

R= solution constant = 0.0821 Latm/Kmol

T= temperature = 312 K

$C=\frac{\pi}{R\times T}$

$C=\frac{5.1atm}{0.0821Latm/Kmol\times 312K}=0.2mol/L$

Thus the equation for calculating the molarity of this solution is $C=\frac{\pi}{R\times T}$

If I have 2 liters of gas held at a pressure of 78 atm and a temperature of 900 k, what will be the volume of the gas if I decre

dangina [55]

Answer:

V2 = 2.88L

Explanation:

P1= 78atm, V1= 2L, T1= 900K, P2= 45atm, V2=? T2= 750K

Applying the general gas equation

P1V1/T1 = P2V2/T2

Substitute the above

(78*2)/900= (45*V2)/750

V2= (78*2×750)/(900*45)

V2= 2.88L
