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. 0.00204 Calculate the moles of CH3COOH in vinegar (mol). Number answer only, do not write units. Do NOT write answer in scientific notation. 0.00204 Calculate the mass of CH3COOH in vinegar in grams (g). Number answer only, do not write units. Do NOT write answer in scientific notation. 0.122 Calculate the percent by mass of CH3COOH in vinegar (%). Number answer only, do not write units. Do NOT write answer in scientific notation. 4
