Answer:

The answer is "23765.4"

Explanation:

Motor weight average number $(\bar{M_n}) = 1000000 \frac{g}{mol}$

Poly condensation degree dependent on the average number of molecular weights is as follows:

$DP_n = \frac{\text{Mol.Wt Number Medium}}{\text{Monomer Unit Mol.Wt}}$

All monomer module, in this case, is propylene

Sunrise. Unit Wt = Mol. Propylene weight

$= \ Mol. \ Wt \ of \ C_3H_6\\\\= 3 \times 12.01 +6 \times 1.008 \ \ \frac{g}{mol}\\\\= 42.078 \frac{g}{mol}\\\\$

$DP_n = \frac{1000000}{42.078}\\\\$

$=23765.4$
