The relative atomic mass of chlorine is 35.5.When calculating relative atomic mass, which particle is the mass of a chlorine atom compared to? A.a neutronB.a protonC.an atom of carbon-12D.an atom of hydrogen-1相关知识点: 试题来源: ...
The atomic mass is measured in Atomic Mass Units (a.m.u.) – a.m.u is a relative scale – The mass of Carbon-12 = 12.0000… amu Carbon-12 vs. Magnesium-24 Average Atomic Mass • Not all isotopes occur naturally in the same proportions – Some isotopes occur more often than ...
make sure you're using molar mass, atomic mass, molecular mass, isotopic mass, relative atomic mass, etc correctly and that you are rock solid on the meaning of those terms!.good luck! Logged calejone New Member Posts: 5 Mole Snacks: +0/-0 Re: Calculating mass of an isotope in ...

field may be used to locate such crossings by choosing the energy of the desired threshold as the reference energy and setting the relative energy to zero. The programs always extract the local wavefunction vector ψ(Rmatch) at the matching point. If desired, they can calculate the complete ...
