Estimate the molecular weight of a polymer if a 100.-mL solution of 6.5 g of the polymer in toluene has an osmotic pressure of 0.044 atm at 27°C.

Question

anonymous · Answer

osmotic pressure= contration*R*temperature..

so find concentration...
den no. of moles.. den molecular weight

anonymous · Answer

Can u show me the steps in solving it?

anonymous · Answer

temp is 300,  r=8.314, osmpotic pressure = 0.044... find c(concen.) out of it..
den c= given mass /molar mass * 10 moles/litre.. find mol. mass.. u already have given mass

Sorry but i dont get it can u
 Show me the formulas to where will i substitute the givens, sorry for the bother

The correct answer is 36000 but i dont know how
