So now we basically want to use all the given info and use our formula for asthmatic pressure and find our molar mass of polymer. Now, first step is let's write down our formula and let's see which ones we have and which ones we don't. So I we have I just simply won. And that's because our polymer doesn't associate into anything. So I is one. Our key in Kelvin is 25 plus 273 gives us 298 Kelvin.
