Question

calculate the mass of one atom of ¹⁴C.????​

Answer 1

Answer:

2.32 . 10^(-23)

Explanation:

Carbon-14 is an isotope of carbon that has a relative atomic mass of 14

Mass of 1 atom of carbon-14

= 14g/mol/6.02.10^(-23)atoms

=2.32 . 10^(-23)

______✔

Answer 2

1 g atom of 14C = 14g = 6.022 x 1023 atoms = 6.022 x 1024 x 8 neutrons

Thus 14 g or 14000 mg have 6.022 x 1024 x 8 neutrons

Therefore 7mg will have neutrons = 6.022 x 1024 x 8 /14000 x 7 = 2.4088 x 1022
