Half-life of the substance is 16 years.

Explanation:

Expression for rate law for first order kinetics is given by:

$t=\frac{2.303}{k}\log\frac{a}{a-x}$

where,

k = rate constant

t = age of sample = 48 years

a = initial amount of the reactant = 240 micrograms

a - x = amount left after decay process = 30 microgarms

$48=\frac{2.303}{k}\log\frac{240}{30}$

$k=\frac{2.303}{48}\log\frac{240}{30}$

$k=0.0433years^{-1}$

b) $t_{\frac{1}{2}}$ of reaction

$t_{\frac{1}{2}}=\frac{0.693}{k}=\frac{0.693}{0.0433}=16years$

Thus half-life of the substance is 16 years.
