Calculate molecular weight of different compounds using its molecular formula or its name. Enter either chemical name or molecular formula and calculate molecular weight
While in a mass analyzer, ions may undergofragmentation,whereby energy is imparted into the ionized analyte, causing internal bonds to break and resulting in the production of multiple independent unconnected chemical species.Fragmentation can occur within different regions of the mass spectrometer and ...
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

Comparison of the difference between the initial mass of the sample and its mass after soaking and drying enabled to indicate the compounds which are susceptible to leaching thereby giving the possibility to reverse the treatment, and those which allow permanent wood protection (Fig. 6). It is ...
where F is the atomic force, r is the atom co-ordinate vector, and m is the atom mass. Given the large number of molecules, the workload is too large for analytical algorithms. Therefore, when studying atom velocities and co-ordinates, the finite difference method is usually employed to ...
The molecular weight of oxygen is 32. One mole of oxygen is therefore a mass of 32 g of oxygen. The molecular weight of several gases is given inTable 7. Notice that the molecular weight of hydrogen is 2. (Minor differences from whole numbervalues are neglected for present purposes.) Thi...
