Acetaldehyde (C₂H4O), an oxidation product of ethanol, is found in every type of wine. On average, red wine contains 30.0 mg of acetaldehyde per liter. What is the molarity of acetaldehyde in a bottle of wine (750. mL)? Do not include units or use scientific notation on your final answer (on the blank).

Calculate the molarity of a solution prepared by dissolving 12.50 grams of NaNO3 in 250. mL of solution? The molar mass of NaNO3 is 85.00 g/mol. Write your answer with the correct units on the blank below.

A chemist prepares a solution of vanadiumIII bromide VBr3 by measuring out 0.50g of VBr3 into a 50.mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of Br− anions in the chemist's solution. Be sure your answer is rounded to 2 significant digits.

The solution was prepared by adding 150 g of sodium hydroxide to 150 g of water, giving a total weight of 300 g. Density of the solution is 1.53 g/mL What is the molarity of the solution? 2. Pause the Student Protocol video at 1 minute 39 seconds. Now use your molarity in the dilution equation to calculate the number of mL you will need to dilute to make 500 mL of a 0.10 M sodium hydroxide solution.

You wish to prepare 100.0mL of an aqueous solution of NaCl (aq) that has a molarity of 0.55 M. What mass (in g) of solid NaCl (s) do you need to weigh out. The molar mass of NaCl is 58.43 g/mol. Report your answer to 4 significant figures.

Suppose 37.3 g of ammonium iodide is dissolved in 300. mL of a 0.60 M aqueous solution of potassium carbonate. Calculate the final molarity of iodide anion in the solution. You can assume the volume of the solution doesn't change when the ammonium iodide is dissolved in it. Be sure your answer has the correct number of significant digits.

A chemist prepares a solution of iron (III) chloride (FeC13) by measuring out 0.30 g of FeCl3 into a 300. mL volumetric flask and filling to the mark with distilled water. Calculate the molarity of Canions in the chemist's solution. Be sure your answer is rounded to 2 significant digits. mol L x10 X Ś

Acetic acid (HC₂H₂O₂) is an important ingredient of vinegar. A sample of 50.0 mL of a commercial vinegar is titrated against a 1.00 M NaOH solution. What is the concentration (in M) of acetic acid present in the vinegar if 5.75 mL of the base is needed for the titration? Be sure your answer has the correct number of significant digits. M X

Consider the formation of chlorine gas, from household bleach (sodium hypochlorite) and hydrochloric acid.   NaClO(aq) + 2 HCl(aq) → Cl2(g) + H2O(l) + NaCl(aq) If 13.5 ml of sodium hypochlorite (d = 1.11 g/ml) reacts with excess hydrochloric acid, what volume of chlorine gas will be collected over water at 20.0 oC?  The lab barometer reads atmospheric pressure to be 755 mm Hg and the water vapor pressure at 20.0oC is 17.5 mm Hg.   Question  options:   4.05 L   4.75 L   4.39 L   4.99 L

In the acid-base neutralization reaction between 0.75 M H2SO4 (aq) and 0.75 M KOH (aq), the acid and base will react in a molar ratio of mole acid to mole base.
