- A solution is prepared by dissolving 155.0 mL of methanol (CH3OH, density = 0.791 g/mL) in 250 mL of water (density 1.00 g/mL) to give a final solution volume of 350.0 mL. Calculate the (a) molarity of the solution, (b) %wt/wt, (c) %wt/vol, (d) %vol/volVinegar 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"?Swimming pool water is often made safe for swimming by treating with chlorine in the form of sodium hypocholrite (NaOCI) solution. If a swimming pool contains 5.62×10^5L of water, what volume of 5.00% NaOCI (by mass) solution is required to produce a sodium hypoclorite concentrarion of 3.00×10^-7 mol /L?

The water-containing tubing was then rinsed, weighed (4.774g) and put into a beaker that contained sugar water. After about an hour, the tubing was removed from the beaker, rinsed and reweighed (4.316g). The determined masses are a. consistent with the expected osmosis that should have occurred b. not consistent with the expected osmosis that should have occurred; the tubing probably leaked c. not consistent with the expected osmosis that should have occurred; the tubing was probably put into pure water rather than sugar water d. not consistent with the expected osmosis that should have occurred; no cause is apparent e. no correct response
