Given the number of moles of benzoic acid necessary to react with 40 mL of a 0.1 M NaOH solution, how many grams of benzoic acid must be added to 100 mL of water to react with a 1:1 stoichiometry with the NaOH? The molecular weight of benzoic acid is 122 g/mol. Report your answer with four digits and a decimal as: 0.123 or 1.234 Do NOT show units (g).

Assume that you have 1.00 $\mathrm{g}$ of a mixture of benzoic acid (molec. mass $=122 \mathrm{amu}$ ) and gallic acid (molec. mass $=170 \mathrm{amu}$ ), both of which contain one acidic hydrogen that reacts with NaOH. On titrating the mixture with $0.500 \mathrm{M} \mathrm{NaOH}, 14.7 \mathrm{mL}$ of base is needed to completely react with both acids. What mass in grams of each acid is present in the original mixture?
Benzoic acid, $\mathrm{C}_{6} \mathrm{H}_{5} \mathrm{COOH},$ is sometimes used as a primary standard for the standardization of solutions of bases. A $1.862-\mathrm{g}$ sample of this acid is neutralized by $35.00 \mathrm{~mL}$ of $\mathrm{NaOH}$ solution. What is the molarity of the base solution?
