According to the collagative properties, the osmotic pressure is equal to crt, where c is the concentration, r is the gas constant and t is the temperature.
00:11
So the value of pi is 62 .9 tor which can be converted into atm by dividing the value of tor by 760.
00:22
So we get the value of osmotic pressure in terms of atm as 0 .08 to atm.
00:30
The value of r is 0 .08206 atm liter per mole per kelvin and t is 25 degrees celsius which is also written as 298 kelvin.
00:48
So we can first calculate the concentration.
00:53
So the concentration would be 0 .082 atm is equal to 0 is equal to c into 0 .0 .0 .0 .0 .0 .0 .0 .0 .0 .m .m.
01:01
8206 atm liter per mole per kelvin into 298 kelvin.
01:12
So the value of concentration would be 0 .0033 mole per liter.
01:20
So this is the value of concentration.
01:23
So for determining the molar mass, what we will do is we will expand the formula of concentration.
01:30
The concentration is equal to given mass.
01:33
Upon molar mass into one upon volume of solution in liter.
01:41
So now we know that that we have 0 .97 gram of solute in one liter of solution...
