Question

The osmotic pressure exerted by a solution is equal to the molarity multiplied by the absolute temperature and the gas constant RSuppose the osmotic pressure of a certain solution is measured to be 22.atm at an absolute temperature of 353.KWrite an equation that will let you calculate the molarity c of this solution. Your equation should contain only symbols. Be sure you define each symbol other than R.

Answer 1

Answer: M = 22/ (i x28.948)

Explanation:

Pi = osmotic pressure = 22atm

T = Temperature = 353K

M = Molarity = ?

R = gas constant = 0.082atm.L/mol/K

i = van’t Hoff factor

Pi = iMRT

M= Pi /(iRT) = 22 / ( i x 0.082 x 353)

M = 22/ (i x28.948)
