High, formula to calculate the osmotic pressure of a solution is pi is equal to c r t where pi represents osmotic pressure, c represents the concentration of solution, r is the universal gas constant and t is the temperature.
00:16
So first of all pi is equal to 83 .4 atmosphere, r is equal to 0 .082 liter atmosphere per mole kelvin and temperature is equal to 20 .4 degree celsius.
00:38
So we add 273 to it to convert it into kelvin.
00:41
So we get 293 .4 kelvin.
00:47
So the concentration of the solution is equal to pi divided by r t.
00:52
Pi is equal to 83 .4 atmosphere divided by 0 .082 liter atmosphere per mole kelvin multiplied by 293 .4 kelvin.
01:06
So upon solving it we get concentration equal to 3 .466 mole per liter.
01:14
So it is the molarity.
01:19
So this concentration that is 3 .466 mole per liter is equal to moles of solute which is an unknown compound...
