Anaesthetic is a used during surgery to cause unconsciousness or a lack of feeling in a part of the body. 42.0 mL of anaesthetic is added to distilled water to make a 200 mL solution. What is the % V/V of the new solution? You must show your work in the space provided and then, record your answer with the correct number of significant digits and proper units. Remember, when giving the units for percent concentration, you need to include the % sign as well as the "type" of percent (W/W or V/V or W/V). For example, 12.1% V/V.

Beakers (a), (b), and (c) are representations of tiny sections (not to scale) of mixtures made from pure benzene and pure water. Select which beaker gives proper representation of the result when the two pure substances are mixed.
Suppose that you are closing a cabin in the north woods for the winter and you do not want the water in the toilet tank to freeze. You know that the temperature might get as low as 30. C, and you want to protect about 4.0 L water in the toilet tank from freezing. Calculate the volume of ethylene glycol (density = 1.113 g/mL; molar mass = 62.1 g/mol) you should add to the 4.0 L water.
If a solid block of glass, with a volume of exactly 100 in.3, is placed in a basin of water that is full to the brim, then of water will overflow from the basin.
A beaker has a mass of 40.94 g. After 5.00 mL of the concentrated hydrochloric acid solution is pipetted into the beaker, the combined mass of the beaker and hydrochloric acid solution is 46.92 g Calculate the density of the hydrochloric acid solution based on the information provided.
An empty beaker is placed on a balance, and its mass is recorded at 42.513 g. The beaker is removed from the balance, and a solution of sodium chloride is then added to the beaker. The beaker with its contents is placed back on the balance, and the new mass is recorded to be 75.841 g. What is the mass of the sodium chloride solution? Remember to include the unit .

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"?
A student is making a solution of NaCl in water. If the student uses 5.56 grams of NaCl and enough water to make 7.63 liters of solution, what is the molarity of the student's salt solution? Round your answer to the nearest 0.01 and include units properly abbreviated, but NOT substance!
