atomic and molecular masses

It is known that the atomic mass of an element/compound is not the mass of one atom or molecule of the said element/compound because they occur as a mixture of isotopes. As the atomic and molecular masses are expressed on a..

The molecular mass of a substance is the relative mass of its molecule as compared with the mass of a 12 C atom taken as 12-units. It indicates the number of times; one molecule of the substance is heavier than atom..

Molecular mass is equal to sum of the atomic masses of all atoms present in one molecule of the substance.Example: H 2 OMass of H atom = 1Mass of 2H atoms = 2Mass of O atom = 16Molecular ..

Molecular mass expressed in grams is numerically equal to gram molecular mass of the substance.Molecular mass of O 2 = 32Gram molecular mass of O 2 = 32gGram molecular mass is the relative molec..

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..

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 mass i..

The molecular mass of a substance is the relative mass of its molecule as compared with the mass of a 12C atom taken as 12-unit..

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..
