Solutions are homogenous while a suspension is heterogenous, which means that you may not observe and differentiate parts of a solution (such as putting salt in water) but you can in suspensions (such as mixing water and sunflower oil).
Answer:
L=7.0125*10^-5
Explanation:
LET
Length of polyethene chain= L
Molecular weight OF polyethene= MW
Molecular weight of monomer =mw
Monomer length= l
L=(MW/mw) *l
L= (28.05g/mol10^6gmol-1) * 2.5
L=70.125*10^-6
L=7.0125*10^-5
Hence, the length will be L=7.0125*10^-5
