(D) For a strong acid like $HBr$,the concentration of $H^+$ ions is given by $[H^+] = 10^{-pH}$.Given $pH = 4$,so $[H^+] = 10^{-4} \ M$.Since $HBr$ is a monoprotic acid,the normality $(N)$ is equal to the molarity $(M)$,so $N = 10^{-4} \ N$.The volume of the solution is $V = 100 \ mL = 0.1 \ L$.The number of equivalents is calculated as $	ext{Equivalents} = N 	imes V 	ext{ (in liters)}$.$	ext{Equivalents} = 10^{-4} 	imes 0.1 = 10^{-5} \ eq$.

Find the number of equivalents of $HBr$ present in $100 \ mL$ of its solution whose $pH$ is $4$.
