The monoisotopic mass of an ion or molecule is defined as an exact mass and is determined by summing each mass of the most abundant isotope (e.g. 1H=1.00782, 12C=12.00000, 16O=15.99491, 14N=14.00307) present in the chemical formula. ...
The mass of a carbon atom is {eq}1.9927 \times 10^{-23} {/eq} g. How many carbon atoms are in a 12 gram diamond? Avogadro's Number: The mass of one atom of an element is equal to the average atomic mass of the element divided by Avogadro'...
When computing the formula mass of an ionic compound, the average masses of neutral sodium and chlorine atoms were used, rather than the masses for sodium cations and chloride anions. Even though a sodium cation has a slightly smaller mass than a sodium atom (since it is missing an electron...
A hydrogen-1 atom has a mass of 1.007 u (or Da or amu). A carbon-12 atom is defined as having a mass of 12 u. The largest known protein, titin, has a mass of 3 x 106Da. AMU is used to differentiate between isotopes. An atom of U-235, for example, has a lower AMU than ...
