In chemistry, the mass number is the total number of protons and neutrons in the nucleus of one atom of a given element. It?s also called the nucleon number, because protons and neutrons are also called 'nucleons.'Answer and Explanation: ...
In chemistry, “mM” stands for millimolar, which is a unit used to express a solute’s concentration in a solution. Explanation: Millimolar (mM) concentrations are often used for convenience when working with solutions of small quantities of substances. One millimolar (1 mM) is equal to one...
weight is properly reported using units of kg·m/s2or Newtons (N). However, since everything on Earth is subject to about the same gravity, we usually drop the "g" part of the equation and just report weight in the same units as mass. It's not correct, but it doesn't cause proble...
In chemistry, there are different types of mass. Often, the terms are called weight rather than mass and used interchangeably. A good example is molecular mass or molecular weight. Molecular Mass Definition Molecular mass is a number equal to the sum of theatomic massesof theatomsin amolecule...
Mass Number It is the sum of neutrons and protons of an atom present in nucleus. Mass Number for two different atoms can be same. The Atomic Mass of an atom is approximately equal to its Mass Number as mass of a neutron as well of a proton is one unit on atomic mass scale. Post ...
