you are experimenting with a radioactive sample of polonium at the en of 14.0 minutes exactly 1/16 of the polonium remains. what is the corresponding halflife of polonium

Respuesta :

Answer:

t(1/2) = 3.5 min

Explanation:

From A = A₀e⁻ᵏᵗ => k = ln(A/A₀)/-t = [ln(1/16)/-14]min⁻¹ = 0.198 min ⁻¹

=> t(1/2) = 0.693/k = (0.693/0.198)min = 3.5min
