What percentage of the mass of a carbon-12 atom is
Lynna [10]

Answer:

% of mass of electrons in C = 0.0272

Explanation:

Atomic no. of carbon = 6

So, no. of electron = 6

Mass of an electron = \frac{1}{1836} amu

Mass of 6 electrons = 6 \times \frac{1}{1836} = 0.003268 amu

Mass of C = 12.0107 u

% of mass of electrons in C = \frac{Mass\ of\ all\ electrons}{Mass\ of\ C}\times 100

% of mass of electrons in C = \frac{0.003268}{12.0107}\times 100=0.0272 \%
