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

How many milliliters of 1.50 M magnesium sulfate soulution is required to supply 2.50 mole of this salt?

arsen [322]

Answer:

1670 ml
