The osmotic pressure pi equal to i m r t where pi is the osmotic pressure, the value will be given 2111 dot divided by 760 dot per atm because it will be the conversion to 2 .77 atm.
00:30
M will be molarity that value will be given 0 .1075 and r will be universal gas constant the value will be 0 .08 to liter atmosphere mole inverse kelvin inverse t will be the temperature that will be the 25 degree centigrade that will give you 25 plus 273 that will be 298 kelvin and i will be the isotonic coefficient that value from this equation will be take pi over m r t.
01:16
Now putting the value of pi that will be 2 .77 atm over m value will be 0 .1075 m into r value 0 .082 into temperature 298 kelvin and r unit of r will be liter atm mole inverse kelvin inverse and kelvin will be cancel out atm and atm will be cancel and we know that and we know that m equal to mole per liter.
01:57
So, m inverse that will be liter into mole inverse.
02:06
So, it will be coming around 1 .05.
02:10
Now we know that isotonic coefficient is associated with degree of dissociation.
02:36
Now concentration of particles that will be concentration of non -dissociative mole plus concentration of ions and concentration of non -dissociative particles that will be concentration of total minus alpha into concentration of total, alpha is the degree of dissociation.
03:02
Now c of ions concentration of ions that will be alpha of total c total plus alpha of c total.
03:13
So, that will be 2 alpha concentration of total particles...
