2 CHEMISTRY-RELATIVE ATOMIC MASSthe 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再给另一个例子不要用英文角度解释...
100分求一道物理题 If the mass of a hydrogen atom is 1.67*10^-27kg and the mass of an electron is 9.1*10^-31kg,how many electrons would be required to have a mass equivalent to one hydrogen atom?
Effects of the finite proton mass of a hydrogen atom in crossed magnetic and electric fields: a state with giant electric dipole - Dzyaloshinskii - 1992I. Dzyaloshinskii, Effects of the finite proton mass of a hydrogen atom in crossed magnetic and electric fields: a state with giant electric ...
What is the mass of a single hydrogen atom?Number of molesThe number of moles can be defined as the ratio of the given mass to the atomic mass, or it can be the ratio of the number of the particles to the Avogadro number.Answer and Explanation: ...

Calculate the mass of 2.5 g atom of oxygen. View Solution The approximate radius of a H-atom is 0.05 nm, and that of proton is 1.5×10−15 m. Assuming both hydrogen atom and the proton to be spherical, calculate fraction of the space in an atom of hydrogen that is occupied by the...
A lower bound value of 1.51, where is the mass of the electron, is obtained for the critical mass at which a hydrogen atom will just form a bound state with a positron. This is slightly above the previous best lower bound value obtained by Aronson, Kleinman, and Spruch. The method ...
The total number of atoms in 1 m3 is then 4×2.14×1028=8.56×1028 since an fcc cell contains four atoms. 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...
12C atom in g? View Solution Assertion(A) One atomic mass unit is defined as one twelth of the mass of one carbon-12 atom. Reason(R) Carbon-12 isotope is the most abundant isotope of carbon and has been chosen as standard. View Solution What is the weight of one atom of Hydrogen ...
