the mass of a hydrogen atom 1/1H is equal to 1/12 of the mass of a carbon-12 atomso its relative isotopic mass is 1.A magnesium atom 24/12Mg is twice as heavy as a carbon-12 atom,so its relative isotopic mass is 24再给另一个例子...
However, this binding energy has a mass equivalence which is smaller than the least significant figure in the calculation. The mass of a neutron is 1.008 665 u while that of the hydrogen atom is 1.007 825 u. Since both neutrons and protons have almost unit atomic masses, the atomic mass ...
atomic mass unit A unit of mass equal to1/12the mass of an atom of the most common isotope of carbon (carbon 12), which is assigned a mass of 12. A hydrogen atom has a mass of 1 atomic mass unit since its mass is1/12the mass of carbon 12. ...
What is the atomic mass of hydrogen?HydrogenHydrogen has three isotopes or different versions of hydrogen. Each of the isotopes has one proton, but different numbers of neutrons. Hydrogen-1 has one proton and zero neutrons. Hydrogen-2 has one proton and one neutron. Hydrogen-3 has one proton...
The atomic mass unit is defined in terms of the stable carbon nuclide 12C, which is assigned an atomic mass of exactly 12.000000 u. Thus the atomic mass unit is by definition exactly 1/12 the rest mass of 12C, or [2.5]1u=1.66053873×10−27kg. The masses of all the nuclides in atom...
What is the binding energy per nucleon of 197 Au (atomic number = 79)? (The following information regarding atomic masses will be needed: 197Au, 196.966 543 u; hydrogen, 1.007 825 u; neutron, 1.008 66 How many atoms are there in the Sun? The mass of the Sun is 1.99*10^30 kg, an...

Furthermore, the mass of a copper atom is 63.57 times the mass of a hydrogen atom (which is 1.63×10−24 g) so that the mass of 1 m3 of copper, i.e. the density, is 8.56×1028×63.57×1.63×10−24=8900 kg m−3. On alloying, the density of a metal changes. This is ...
