Dear students, mass of the compound is 15 .2 gram, volume of solution 150 ml, temperature 25 degrees celsius, osmotic pressure 8 .44 torque.
00:10
And we have to calculate molecular mass of the molecular compound.
00:15
We know osmotic pressure pi equal to cm, r t, where cm is the concentration, molar concentration, r is the gas constant, universal gas constant, and t is the temperature.
00:27
Or, we have given pi is 8 .44 tor.
00:33
So in atmosphere, it is 8 .44 divided by 760 multiplied by molarity of the solution.
00:41
Molarity means mass of the solute multiplied by 1 ,000 divided by molar mass...
