belka [17]

<u>Answer:</u>

t = 6.3 days

<u>Step-by-step explanation:</u>

The amount of initial mass is irrelevant when finding the half-life since the remaining mass is always 1/2 of the initial mass.

$\frac { 1 } { 2 } = e ^ { ( - 0 . 1 0 9 2 t ) }$

Taking $l n$ on both the sides to get:

$ln \frac { 1 } { 2 } = -0.1092t$

$t = \frac { l n \frac { 1 } { 2 } } { -0.01092}$

$t = 6.3475$

t = 6.3 days
