How to Find Molecular Weight

The molecular mass, often called the molecular weight (MW), is the weight of all atoms in a given molecular formula. Molecular weight is measured in Atomic Mass Units, usually expressed as u or amu. In order to calculate the molecular...

$Down in the lab today bagging spent resin. This is frankincense after hydrodistillation. The volatile fraction has been removed but the resin body remains chemically complex. During distillation heat and water volatilize low molecular weight compounds like monoterpenes and sesquiterpenes. These are aromatic. They enter the vapor phase and become essential oil. Boswellic acids do not. Their molecular weight is too high and they are not volatile. They stay locked in the resin matrix. What distilla$
