Final answer:
To calculate the grams of benzoic acid needed to react with 20.00 mL of NaOH solution, the molarity of NaOH is necessary. The steps include calculating the moles of NaOH, using the molar ratio between the reactants, and converting the moles of benzoic acid to grams. However, without the molarity of the NaOH solution, the correct answer cannot be determined from the options provided.
Step-by-step explanation:
To determine how many grams of benzoic acid are necessary to react with 20.00 mL of NaOH solution, one must first know the concentration of the NaOH solution. Since this information is not provided in the question, we cannot give a definitive answer. If we assume that the student has the molarity of the NaOH solution, the calculation would consist of several steps:
-
- Determine the number of moles of NaOH using the volume and molarity of the NaOH solution provided.
-
- Use the molar ratio from the balanced equation of the reaction between benzoic acid and NaOH, which is typically 1:1.
-
- Convert the moles of benzoic acid to grams using the molar mass of benzoic acid which is 122.12 g/mol.
Without the molarity of the NaOH solution, it is not possible to select the correct answer from the options given.
