Molecular weight is measured in Atomic Mass Units, usually expressed as u or amu. In order to calculate the molecular weight of a formula, you'll need to add up the atomic masses of each element present. The molecular weight of nitrogen, N2, is 28 g/mol. What is the rms speed of nitrogen molecules in a cooler at 8.0°C? The Boltzmann constant is 1.38 × 10-23 J/K and NA = 6.022 × 1023 molecules/mol. 2009-01-21 · You need to give me the Atomic mass unit and the molecular mass of Nitrogen. Lets say its 14g/mol.

Calculation. Molecular masses are calculated from the atomic masses of each nuclide present in the molecule, while molar masses are calculated from the standard atomic weights of each element.The standard atomic weight takes into account the isotopic distribution of the element in a given sample (usually assumed to be "normal"). For example, water has a molar mass of 18.0153(3) g/mol, but
