Question

calculate the mass of 1 atom of c14

Answer 1

As C-14 atom 6 protons and 8 neutrons. it's mass number is 14.

Answer 2

Carbon-14(C-14) has 6 protons and 8 neutrons and therefore it has an atomic mass of 14.

1 mole of C-14 has 6.023 × 10^23 atoms

Therefore, the mass of 1 atom of C-14 is :

14/ 6.023×10^23 = 2.32 × 10^-23 g

Therefore, the mass of 1 atom of C-14 is 2.32×10^-23.

The value 6.023 × 10^23 is also known as the Avogadro's constant and in order to find the mass of 1 atom of any substance, we can just divide the atomic mass by the Avogadro's constant.
