The concentration of sodium hydroxide solution is calculated:
[NaOH] = g / MM * V = 4.6556 / 40 * 0.5 = 0.23278 M
The moles of NaOH used are calculated:
n NaOH = M * V = 0.23278 * (43.74 - 2.38) / 1000 = 0.00963 mol
The mass of benzoic acid is calculated:
m = n * MM = 0.00963 mol * 122.12 g / mol = 1,176 g
If you liked the answer, please rate it positively, you would help me a lot, thanks.

Question 4 (1 point) 0.444 g of an unknown diprotic acid is dissolved in about 60 mL of water in a beaker. The solution is transferred to a 100.00 mL volumetric flask, which is then filled up to the mark. The solution is mixed by inverting multiple times. 25.00 mL of this solution is then transferred to an Erlenmeyer flask for the titration. What mass of the diprotic acid is in the 25.00 mL that is transferred? Provide your answer...

Below are hypothetical data from a titration experiment. Part A focuses on determining the molarity of a sodium hydroxide solution. Part B uses the sodium hydroxide solution to determine the molarity, and ultimately the mass percent, of acetic acid in an unknown vinegar sample. Vinegar is an aqueous solution containing 4 to 6% by mass acetic acid. Please use the data provided below to perform the calculations and answer the questions in this assignment. Part A: A 0.883 M standard...

0.408 g of an unknown triprotic acid are used to make a 100.00 mL solution. Then 25.00 mL of this solution is transferred to an Erlenmeyer flask and is titrated with 0.1125 M NaOH. The initial burette reading is 0.82 mL; when the titration endpoint is reached, the final burette reading is 37.62 mL. How many moles of triprotic acid are neutralized during the titration? Provide your answer in decimal form (e.g. 0.123) to the correct number of significant figures.
