The radioactive element​ carbon-14 has a​ half-life of 5750 years. a scientist determined that the bones from a mastodon had los
Monica [59]
Radioactive elements obey 1st order  kinetics,

For 1st order reaction, relation between rate constant (k) and half life [t(1/2)] is,
k = \frac{0.693}{t(1/2)} =  \frac{0.693}{5750} = 1.205 X 10^-^4 hr^-^1

Also, for 1st order reaction, we have
t = \frac{2.303}{k} log  \frac{\text{initial conc.}}{\text{final conc.}}
 
Given that: <span>the bones from a mastodon had lost 78.5​% of their​ C14,
</span>∴ initial conc. of C14 = 100%, conc. of C14 left after time 't' = 21.5%

∴t = \frac{2.303}{1.205 X 10^(-4)} log \frac{\text{100}}{\text{21.5}} = 1.2758 X 10^4 hours
