Once the relative mass scale was made, later experiments were able to relate the mass in grams of a substance to the number of atoms and an atomic mass unit—amu was found; 1 amu or Dalton is equal to 1.66×10-24 grams. At this time, chemists knew the atomic masses of elements and...
So how much is a mole? When we're talking about atoms, a mole is the relative atomic mass in grams. So a mole of carbon is 12g, because carbon's relative atomic mass is 12, and it contains 620 billion trillion atoms. A mole of aluminum is 27g, because aluminum's relative atomic ...

In physics, mass is defined as the amount of force required to cause a body to accelerate. Mass is very closely related to energy in physics. Mass is dependent on the body's motion relative to the motion of an observer. If the body in motion measured its mass, it is always the same...
What is relative atomic mass? If the atomic mass of an element is x, what is the mass in grams of 6.02 X 10^{23} atoms of the element? What is the mass number of iodine? What is the mass number of strontium? What is the mass number of an electron? What is the mass number of...
Within the framework we just developed, any property is a function of the phase space of nuclei, which also parametrically depends on the properties of the corresponding atoms, e.g., their mass, effective charge, etc. Thus, the generic property reads\(A({\pmb \Gamma }; \{m_{\alpha }...
Landsberg stated that, while this definition is mathematically correct, it contradicts the statistical definition of temperature, which comes from the study of the relative motion of a large number of particles with respect to their center of mass. Therefore, all statistical definitions can not ...
In the process of so doing, most of the charge that flowed through the capacitor when the electric field was applied is returned to the circuit, flowing in the opposite direction. A material’s (relative) dielectric constant describes the extent to which a material facilitates this temporary ...
By varying the magnetic field in the mass spectrometer, ions of different mass-to-charge ratio will be deflected into the detector, producing a charge proportional to the number of ions. This spectrum can then be used to determine the relative amount of isotopes of an atom, to identify chemic...
