Answer:
Three types of metamorphism exist: contact, dynamic, and regional. Metamorphism produced with increasing pressure and temperature conditions is known as prograde metamorphism.
Answer:
The answer is "23765.4"
Explanation:
Motor weight average number 
Poly condensation degree dependent on the average number of molecular weights is as follows:

All monomer module, in this case, is propylene
Sunrise. Unit Wt = Mol. Propylene weight
