i need a help to solve my polymer hw

 

q1)estimate the degree of polymerization of with an average molecular weight of 150,000 the molecular weight of an ethylene monomer is 28

 

 q3)to enhance processability of a polymer why would you want to decrease its molecular weight?
 

q7)increasing the molecular weight of of a polymer increases its strength and stiffness, as well as its viscosity. is too high of a viscosity a limiting factor when increasing the strength by increasing the molecular weight? why?
