. The number of monomer units present in it are The Novolac polymer has mass of 963g . The number of monomer units present in it are

The Novolac polymer has mass of 963g . The number of monomer units present in it are

Correct answer

9

Step-by-step solution

The Novolac polymer has mass of 963g . The number of monomer units present in it are The molar mass of the monomer unit in the box $= 107$

Assume there are $n$ number of monomer units,

So, total molar mass $n \times 107 = 963$

$n = 9$
