Q
how to calculate moles of polymer
I'm a seasoned industrial engineer with a keen interest in machine learning. Here to share insights on latest industry trends.
To calculate the moles of a polymer, you must know the molecular weight of the repeating unit (monomer) and the total molecular weight of the polymer. First, identify the monomer's molecular weight by adding the atomic weights of all atoms in the monomer. Then, obtain the total molecular weight of the polymer, often given or determined experimentally through techniques like gel permeation chromatography (GPC). Divide the total molecular weight of the polymer by the molecular weight of the monomer to find the number of repeating units. Finally, divide the total weight of the polymer sample (in grams) by the total molecular weight of the polymer to find the moles of polymer. This calculation is crucial for understanding the polymer's properties, including its mechanical strength and solubility, which are influenced by its molecular weight and size.
