A polymer contains 0.16% of sulphur by weight. What is the minimum molecular weight of the polymer.

Text Solution

Verified by Experts

Each molecule of the given polymer must contain at least one S-atomm.
in other words, each gram-mole of the polymer ust contain at least 32g of sulphur.
But, 0.16g sulphur is present in 100g of the polymer.
`therefore` 32g sulphur is present in `(100xx32)/(0.16)=20000g` of the polymer.
thus, minimum molecular weight of hte polymer is 20,000.
