A mole contains Avogadro’s number of particles of a substance.
Answer:
Explanation:
Hello there!
In this case, since the radioactive decay is considered as first-order kinetic model, whereby the remaining mass of the radioactive material involves the initial one, the rate constant and elapsed time:
As we were not initially given the rate constant, we can use the half-life to calculate it as follows:
Thus, we can calculated the elapsed time for the given conditions to obtain:
Regards!
When an atom undergoes radioactive decay which is where it spontaneously emit matter and energy from its nucleus, the part of the atom that is affected is the nucleus as it is known to breakdown due to the instability it possesses because of the neutron to proton ratio. This matter and energy is released as the atom hopes to attain stability- transmutes from one element to the next, and will continue emission until it does attain stability.
