<em>The number of atomic orbitals is the same for all elements in a period. Every element in the top row (the first period), for example, has only one orbital for its electrons. The electrons of all the elements in the second row (second period) have two orbitals. Every row adds an orbital as you progress down the table.</em>

Explanation:
We use the equation:
Mass = Number of moles * Molecular or atomic mass
Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement.
Number of particles in 1 mole = 6.023 × 1023
Mass of 1 electron = 9.10938 × 10-28 gm
Mass of 1 mole of electrons = 6.023 × 1023 × 9.10938 × 10-28 = 5.486 × 10 -4
Mass of 1 proton = 1.67262 × 10 -24 gm
Mass of 1 mole of protons = 6.023 × 1023 × 1.67262 × 10 -24 gm = 1.007 gm
Mass of 1 neutron = 1.67493 × 10-24 gm
Mass of 1 mole of neutron = 1.67493 × 10-24 × 6.023 × 1023 = 1.008 gm
