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
