12C,the molar mass of any substance is numerically equivalent to its atomic or formula weight in amu. Per the amu definition, a single12C atom weighs 12 amu (its atomic mass is 12 amu). According to the definition of the mole, 12 g of12C contains 1 mole of12C...

Molar Mass (Molecular Weight) - The term mole also referred to as mol was first used by Ostwald in 1896. The mass in g of 1 mole of a substance is known as the molar mass or molecular weight of the substance. The molar mass of any substance can be calcul

Molecular weight, mass of a molecule of a substance, based on 12 as the atomic weight of carbon-12. It is calculated in practice by summing the atomic weights of the atoms making up the substance’s molecular formula. The molecular weight of a hydrogen m

The aim is to study the coupling between a continuum ensemble of particles that participate into a small number of rare events, representing the binding of a small and finite tiny subset of these Brownian mole- cules to small targets. It was already noticed that discrete-state stochastic models...
