Suppose the half$-$life is $48\mathrm{.}1$ s Suppose the half$-$life is $48\mathrm{.}1s$ for a first order reaction and the reactant

concentration is $0\mathrm{.}0617M65\mathrm{.}8s$ after the reaction starts. How many seconds after

the start of the reaction does it take for the reactant concentration to decrease to

$0\mathrm{.}0115M?$for a first order reaction and the reactant concentration is $0\mathrm{.}0617$ M $65\mathrm{.}8$ s after the reaction starts. How many seconds after the start of the reaction does it take for the reactant concentration to decrease to $0\mathrm{.}0115$ M$?$
