what is the mass of benzoic acid required to react with 20 ml of a .100 M sodium hydroxide solution
Added by Brooke M.
Step 1
First, we need to know the reaction between benzoic acid and sodium hydroxide. The reaction is as follows: C6H5COOH + NaOH -> C6H5COONa + H2O From the reaction, we can see that one mole of benzoic acid reacts with one mole of sodium hydroxide. Show more…

EXPERIMENT 1: How many grams of benzoic acid are necessary to react with 20.00 mL of the NaOH solution? The molar mass of benzoic acid is 122.12 g/mol. Choose the closest answer. Select one: 6.13 g 0.127 g 0.244 g 0.22 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?
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).
