![A commercial vinegar is analyzed for the percent acetic acid present. The data for the first trial is given below. Calculate the required quantities using the raw data below.
Preparation of Vinegar Sample:
• Mass of vinegar (g) = 3.06
Analysis of Vinegar Sample:
• Buret reading, initial (mL.) = 25.40
• Buret reading, final (mL) = 3.70
• Molar concentration of NAOH solution (mol/L) = 0.0940
Calculate the volume of N2OH used (mL).
Number answer only, do not write units. Do NOT write answer in scientific notation.
21.7
Calculate the moles of N2OH added (mol).
Give answer with at least three significant figures. Take note that number of significant figures is not necessarily the
same as number of decimal places.
Number answer only, do not write units. Do NOT write answer in scientific notation.
