Molar mass neon = <span>20.1797 g/mol
20.1797 g ---------- 6.02x10</span>²³ atoms
? g ------------ 3.0 x 10²³ atoms
mass = 3.0 x 10²³ * <span>20.1797 / 6.02 x 10</span>²³
mass = 6.054x10²⁴ / 6.02 x 10²³
mass = 10.05 g
hope this helps!

Answer:
A)It has too many neutrons
Explanation:
Electrons are emitted from the nucleus when a neutron is converted to a proton, an electron and a neutrino. This process is popularly known as beta emission. It reduces the neutron-proton ratio of a nuclide. The neutrino is a particle of zero mass and zero charge that carries off the excess energy and balances spins.
The loss of an electron from the nucleus occurs when there are too many neutrons in the nucleus. The process of beta emission usually reduces the number of neutrons in an atom thereby decreasing the neutron-proton ratio.
Cd(NO₃)₂ - cadmium nitrate
n{Cd(NO₃)₂}=1 mol ⇒ n(N)=2*1= 2 mol
m(N)=n(N)*A(N)
m(N)=2*14.01=28.02 g
