Element X decays radioactively with a half life of 9 minutes. If there are 610grams of
Nookie1986 [14]

A half-life of 9 minutes corresponds to a decay factor <em>k</em> such that

\dfrac12=e^{9k}\implies k=-\dfrac19\ln\left(\dfrac12\right)

Then the time it takes for the substance to decay from 610 g to 124 g is time <em>t </em>such that

124\,\mathrm g=(610\,\mathrm g)e^{kt}

Solve for <em>t</em> :

\dfrac{62}{305}=e^{kt}

\ln\left(\dfrac{62}{305}\right)=kt

t=\dfrac1k\ln\left(\dfrac{62}{305}\right)\approx20.686

so it takes about 20.7 min for the 610 g sample to decay down to 124 g.
