1 s). Given that T1/2 = ln(2) / λ, we can rearrange the equation to solve for λ: λ = ln(2) / T1/2 λ = ln(2) / 12.1 λ ≈ 0.0572 s^-1 Show more…

(co) Figure $42-19$ shows the decay of parents in a radioactive sample. The axes are scaled by $N_{s}=2.00 \times 10^{6}$ and $t_{s}=10.0 \mathrm{~s}$. What is the activity of the sample at $t=27.0 \mathrm{~s}$ ?
The results of activity measurements on a radioactive sample are given in the table. (a) Estimate the half-life of the sample. (b) Find the sample.'s decay constant. (c) How many radioactive nuclei were present in the sample at $t=0 ?$ (d) How many were present after 7.0 $\mathrm{h}$ ?
