Question:
The average molar mass of a sample of polypropylene was determined by measuring the osmotic pressure of 500. mL of a solution of 3.16 g of polypropylene in benzene. A pressure of 0.0112 atm was observed at 25°C.
(a) What is the average molar mass of the polymer?
(b) How many propene monomer units with formula OCH(CH3)CH2O were combined on average to create each chain?
(c) If this sample consists only of linear chains and the carbon–carbon bond lengths in the polymer are close to their average value, what is the average chain length?

I have done job as Embedded System Engineer for just four months but after it i have decided to open my own lab and to work on projects that i can launch my own product in market. I work on different softwares like Proteus, Mikroc to program Embedded Systems. My basic work is on Embedded Systems. I have skills in Autocad, Proteus, C++, C programming and i love to share these skills to other to enhance my knowledge too.
