Vinegar is a solution of acetic acid (the solute) in water (the solvent) with a solution density of 1010 g/L. If vinegar is 0.80 M acetic acid, what is the % by mass concentration of acetic acid in vinegar? Hint: Write down what you know with full units to figure out how to do this and remember that vinegar is acetic acid diluted in water and % by mass of vinegar = mass of HC2H3O2 x 100 mass of vinegar How would each of the following errors affect the experimental value of your molarity of acetic? Would your Molarity value be too high, too low, or unaffected? Explain your answer. if you titrated your acid sample to a bright pink rather than faint pink endpoint? if your "acetic acid" burette was still wet inside with deionized water when you filled it with acetic acid? if you recorded the final volume of NaOH as "39.88 mL" instead of "38.88 mL"?

he Don Juan Pond in Antarctica has one of the highest salt concentrations of any natural body of water on Earth. Even though it is in one of the coldest places on the planet, it almost never freezes due to this high salt content. The density of the pond water averages 1.3 g/mL. a.) Calculate the mass (in grams) of 1 gallon of water from the Don Juan Pond. b.) The dissolved salts are dominated by calcium chloride and the pond water is 44% salt by mass. What is the mass (in grams) of the salt in 1 gallon of the pond water? c.) If the salt is all CaCl2, what would be the molarity of the pond water?
