combining weight,eq,equivalent weight,equivalent- the atomic weight of an element that has the same combining capacity as a given weight of another element; the standard is 8 for oxygen meq,milliequivalent- one-thousandth of an equivalent
1/12 the mass of a neutral atom of 12C, equal to 931.5 MeV. Atomic number (Z) Integer equal to the number of protons in a nucleus; the order of an element in the periodic table. Atomic weight or nuclear mass number (A) An integer equal to the sum of the number of protons Z and...
The number of neutrons can change and will determine which isotope of that element the atom will be. Answer and Explanation: 1 The mass number of an oxygen atom with seven neutrons would be 15 and would be an atom of the oxygen-15 isotope. For all oxygen atoms, the nucleus...Becom...
It is important to realise that each unique fragment ion is produced by a single peptide backbone cleavage of a single precursor ion. This means that instead of a single precursor ion, multiple precursor ions, ie, with identical mass-to-charge ratio, are used to generate a single ...
∴ Gram atomic mass of oxygen = 16 g. Molecular Mass The molecular mass of a substance is the number of times the molecule of the substance is heavier than one-twelth the mass of an atom of carbon -12. Or, the molecular mass is equal to the sum of its atomic masses of all the a...
aGiven the atom and mass ratios of X to oxygen, you need to figure out the mass of X that combines with 47.998 u O, i.e., the mass of three O atoms. At this point you divide by 2 and the result should appear some place in the periodic table! 假使X原子和大量比率氧气,您需要推测...
The answer to ‘what is atomic mass’ is this: the total mass of the protons, neutrons, and electrons in a single atom when it is at rest. This is not to be associated or mistaken for atomic weight. Atomic mass is measured by mass spectrometry. You can figure the molecular mass of ...
For example, one molecule of nitric acid (HNO3) contains one nitrogen atom weighing 14.01 amu, one hydrogen atom weighing 1.008 amu, and three oxygen atoms weighing (3 × 16.00 amu) = 48.00 amu. The formula mass of nitric acid is therefore (14.01 amu + 1.008 amu + 48.00 amu) = 63.02...
The optical spectrometer resolves a beam of light into components according to their wavelengths; a mass spectrometer resolves a beam of positive ions into components according to their mass/charge ratio or, if all carry single elementary charges, according to their masses. As with the optical spe...
