It is 1.992648 xx 10^(-23) g ~~ 1.99 xx 10^(-23)g It can be obtained by dividing gram atomic mass of carbon (12 g) with Avogadro's No. (N(A)) ((12g))/(6.022xx10^(23))~~1.99xx10^(-23)g.
The mass of one C atom is: A6.023×1023g B1.99×10−23g C2.00g D12 gSubmit Assertion : One atomic mass unit is defined as one twelfth of the mass of one C-12 atom. Reason : C-12 is the least abundant isotope of carbon and has been choosen as the standard. AIf both asser...

What mass of carbon has the same number of atoms as 78.54 grams of chromium? Molar Mass The molar mass of an atom or a compound is the mass of one mole of that compound. The molar mass of the atom or compound can be used as a conversion factor to convert the mass of th...
Carbon-12 The most common carbon isotope is carbon-12. Its name signifies that its nucleus contains six protons and six neutrons, for a total of 12. On Earth, carbon-12 accounts for almost 99 percent of naturally occurring carbon. Scientists use atomic mass units, or amu, to measure the ...
The atomic mass is the mass of an atom. Although the SI unit of mass is the kilogram, the atomic mass is often expressed in the non SI-unit dalton, where one dalton is defined 1/12 of the mass of a single carbon-12 atom, at rest. The protons an...
