2.) Vinegar is an aqueous solution (homogenous mixture) of acetic acid and water (aqueous="aqua"= Latin for water). To simplify the calculations let us assume that all of the acetic acid in the vinegar reacts and there is some left over "excess" baking soda. The vinegar solution is a 5% acetic acid solution. If you look at the bottle of vinegar somewhere on there it probably says "5% acidity" or similar notation. Let us estimate that about 25.0 g of vinegar...
CHEM 110 Online Lab Instructions for Exp 6 Molar Masses as Conversion Factors Part 1: The Chemical Reaction LET'S WATCH THE BALLOON INFLATE Let us do a simple "chemical reaction and see what happens when these two common household chemicals are put together: vinegar (HC,H,O2 -aqueous acetic acid solution) and baking soda (NaHCO, --sodium bicarbonate). Vinegar is a solution of acetic acid and water. Vinegar is used in salad dressings, to dye eggs, and in other cooking uses. Baking soda...
Vinegar is a solution of acetic acid. Acetic acid has a 1:1 ratio when reacted with NaOH. a. Suppose that the molarity of acetic acid in vinegar is 0.5 M, how many grams of acetic acid are present in the 5 ml of vinegar solution used in the titration? (molar mass of acetic acid = 60 g/mol). b. If vinegar has a density of 1.01 g/mol. Calculate the % of acetic acid in vinegar by mass.
4. Vinegar is a solution of acetic acid. Acetic acid has a 1:1 ratio when reacted with NaOH. a.

Vinegar is a solution of acetic acid in water. If a 325 mL bottle of distilled vinegar contains 18.3 mL of acetic acid, what is the volume percent (v/v) of the solution?
Vinegar is a solution of acetic acid in water. If a 145 mL bottle of distilled vinegar contains 34.2 mL of acetic acid, what is the volume percent (v/v) of the solution? Express your answer to three significant figures.
1. A vinegar solution is 4.00% acetic acid by mass. If the solution has a density of 1.04 g/mL, what is the [HC2H2O2) in the solution?
Calculate the moles of acetic acid, molarity of the vinegar solution, and mass %. of acetic acid in the vinegar using the average of three good trials used to titrate 5.00 mL of the vinegar. You may assume that the density of your vinegar sample is 1.01 g mL^-1. Drain off unused NaOH solution into a clean container and place it into a designated container. Wash the buret two times with regular tap water, then rinse with deionized water, and...
2. What [acetic acid]initial would yield a solution with a pH of 4.50? If vinegar is found to contain 6.0 % acetic acid by mass, what mass of this vinegar (grams), when diluted with sufficient water, would yield 1.0 L of a solution with a pH of 4.50? g vinegar
