An acid-base titration was used to find the percentage of $\mathrm{NaHCO}_{3}$ in $0.310 \mathrm{~g}$ of a powdered commercial product used to relieve upset stomachs. The titration required $14.3 \mathrm{~mL}$ of $0.101-\mathrm{M} \mathrm{HCl}$ to titrate the powder to the equivalence point. Assume that the $\mathrm{NaHCO}_{3}$ in the powder is the only substance that reacted with the titrant. Calculate the percentage of $\mathrm{NaHCO}_{2}$ in the powder.
