Explanation:
Percentage ethylene by weight = 57%
Percentage propylene by weight = 43%
Suppose in 100 grams of polymer:
Mass of ethylene = 57 g
Mass of propylene = 43 g
Moles of ethylene = 
Moles of propylene = 
1 mole = 
molecules/ atoms
Units of ethylene = 
Units of propylene = 
a) Fraction of ethylene units:
b ) Fraction of propylene units:
<em>hey, im jordan :)</em>
the SI unit for the mass of subatomic particles is <u>amu (atomic mass unit)</u>

CFCs and their associated compounds were developed in the early 1900s as a non-toxic, non-flammable solution to other more dangerous products such as ammonia.

Answer- 1 mole
No it is not likely. That is a ratio of 10:4 N^14 and N^15 which doesn’t work. It needs a higher amount
