difference between average mass and relative mass

A proton is actually a hydrogen atom, which has lost its electron. Since the mass of an electron is small, the mass of a proton is equal to the mass of a hydrogen atom. As the mass of hydrogen atom is 1 a.m.u., the relative mass of a prot..

An indirect method to determine the absolute mass of an atom has been devised. The mass of a particular atom is taken as a standard unit and the masses of other atoms are related to this standard. Hydrogen being the lightest element and being the smallest ato..

Relative Molecular Mass - Relative molecular mass or RMM is the molecular weight of an element or an compound. It is the number of times one molecule of the substance is heavier than 1/12 the mass of an atom of carbon (C 1 2 ). Gram molecular m..

Relative molecular mass shows the number of times a molecule is denser than a hydrogen atom or one amu. It is expressed as the ratio of the mass of a molecule of a substance to the mass of one amu (or to one atom of hydrogen..

It is very difficult to accurately weigh the number of atoms as they are extremely light and small and they cannot be seen. Indirect methods have been utilized to determine the absolute mass of an atom...

Relative molecular mass or RMM is the molecular weight of an element or a compound. It is the number of times one molecule of the substance is heavier than 1/12 the mass of an atom of carbon ( 12 C..

Einstein derived a formula given the relation between mass and energy as E = mc 2 . Here 'm' is the mass, 'c' is the velocity of light and 'E' is the energy. This equation has given equal states to mass and energy. It states that a mass m has energy..

Relative molecular mass is the ratio of the mass of one molecule of a substance to the mass t h of a carbon atom, or 1 am..

The atomic mass of an element is a relative quantity and is the mass of one atom of the element relative to 1/12 the mass of one carbon-12 atom. Thu..
