So here in this question, we have been given stonium sulfate at 25 degree celsius and 21 tor of pressure.
00:16
Now, first we have to convert this tor into millimeter of mercury.
00:23
Therefore, we will divide it by 760 millimeter of mercury that comes out to be 0 .03.
00:32
Now we have the formula that is osmotic pressure is equals to i that is vent of factor and that is solubility r that is universal gas constant and t that is temperature the temperature we have been given is 25 degrees celsius therefore first we will convert this is this temperature in kelvin that is 273 plus 25 that is 298 kelvin now, vent -off factor for stanchium sulfate is 2.
01:22
That means, i is equal to 2.
01:26
This is 2 because when this stoncium sulfate splits apart, this forms sr2 plus or so4 to minus.
01:36
Therefore, went -off factor is the charge present over the compound.
01:41
Now, from here, i is equal to 2...
