Question
Chapter 21.3, Problem 1PPA
Interpretation Introduction
Interpretation:
The given concentration of radon after 2.4 days is to be calculated.
Concept introduction:
Radioactivity of an element can be measured as:
lnNtN0=−kt
Here, Nt and N0 is the concentration at a certain time and, at time equals to zero respectively.
Radon has a half-life of 3.8 days.
Half-life is the amount of time required for half of a substance to undergo some specified process.
Half-life for the first order reaction is given as follows:
t12=0.693k
