V= d/t
v=speed
d=distance
t=time
So v= 422/3
v =140.667m/s
After 3 years, the substance will go through 4 half lives. You can do 230*(1/2)^4, which is 14.375.
The Aufbau principle states that, hypothetically, electrons orbiting one or more atoms fill the lowest available energy levels before filling higher levels (e.g., 1s before 2s). In this way, the electrons of an atom, molecule, or ion harmonize into the most stable electron configuration possible.
I believe you just look at your periodic table for this value. I don't think there is any math involved.
Therefore one mole of Mg = 24.305g.
