There are 4 easy steps to find the molar mass of HOC6H5 based on its chemical formula. 1. Count The Number of Each Atom The first step to finding the molar mass of Phenol is to count the number of each atom present in a single molecule using the chemical formula, HOC6H5: ...
In general, the solubility of lignin moiety is defined by the chemical structure, namely, molar mass, number of functional groups, and content of impurities (e.g., carbohydrates) (Brodin et al. Impact of Molecular Weight of Kraft Lignin on Adhesive Performance of Lignin-Based Phenol-Formaldehyde...
