Question

A polymer consists of 8 atoms of sulphur per molecule which is 2% by mass the molar mass of the polymer is

Answer 1

Answer:

The molar mass of the polymer is 12800 g/mol.

Explanation:

Number of sulfur atoms in a molecule = 8

Mass of the polymer = M

Percentage of sulfur in  a polymer = 2

$2=\frac{8\times \text{ atomic mass of sulfur}}{M}\times 100$

$2=\frac{8\times 32 g/mol}{M}\times 100$

M = 12800 g/mol

The molar mass of the polymer is 12800 g/mol.

Answer 2

Answer:

The molar mass of the polymer is 12800 g/mol.

Explanation:

Number of sulfur atoms in a molecule = 8

Mass of the polymer = M

Percentage of sulfur in  a polymer = 2

M = 12800 g/mol

The molar mass of the polymer is 12800
