Molecular Weight of Mer - Calculate PTFE Mer Weight

[Steel_City82]

How would i calculate the weight of a mer, for example a mer of PTFE.

 

[Gokul43201]

The repeat unit (or mer block) in PTFE is -C(F₂)-C(F₂)-

So, all you want is the molar mass of C₂F₄.

The molecular weight of a mer is typically calculated by adding together the atomic weights of the individual atoms that make up the mer. In the case of PTFE (polytetrafluoroethylene), the molecular formula is (C2F4)n, where n is the number of repeating units or mers.

To calculate the molecular weight of PTFE, we first need to determine the atomic weights of carbon (C) and fluorine (F). The atomic weight of carbon is 12.01 g/mol and the atomic weight of fluorine is 19.00 g/mol.

Next, we need to determine the number of atoms of each element in a single mer of PTFE. In this case, there are 2 carbon atoms and 4 fluorine atoms per mer. Therefore, the total atomic weight of a single mer of PTFE can be calculated as:

(2 x 12.01 g/mol) + (4 x 19.00 g/mol) = 24.02 g/mol + 76.00 g/mol = 100.02 g/mol

This means that the molecular weight of a single mer of PTFE is 100.02 g/mol. To calculate the weight of a specific number of mers, we can simply multiply the molecular weight by the number of mers. For example, if we wanted to calculate the weight of 10 mers of PTFE, the calculation would be:

10 mers x 100.02 g/mol = 1000.2 g/mol

Therefore, the molecular weight of PTFE mers is 100.02 g/mol and the weight of a specific number of mers can be calculated by multiplying the molecular weight by the number of mers.
