4 Ans.
The vinegar solution has 5% (v/v) acetic acid. That means, there are 5 mL of acetic acid in 100 mL vinegar solution.
In 15.0 mL solution of vinegar, 5% volume of it is acetic acid.
Therefore, volume of acetic acid is
Therefore, 0.75 mL is acetic acid.
Given that, density of acetic acid is 1.05g/mL. It means, every mL of acetic acid weighs 1.05g.
Therefore, amount of acetic acid in 0.75mL acetic acid is
Therefore, there are 0.788g of acetic acid in 15.0 mL of vinegar solution.
5 Ans.
Molar mass can be calculated by adding the atomic mass of each of the atoms in the compound. If two atoms of the same element is present, then the atomic mass is multiplied by 2 and added to the other atomic masses.
Molar mass od acetic acid, CH3COOH is
There are 2 atoms of C, 4 atoms of H and 2 atoms of O.
Therefore, the molar mass of acetic acid is 60g/mol.
Molar mass of sodium bicabonate, NaHCO3 is
Therefore, the molar mass of sodium bicarbonate is 84g/mol.
5% acetic acid in water. This is a volume percent (v/v) which means there are 5...
Vinegar is sold as % acidity which means a weight/volume or w/v% calculation. The density of acetic acid is 1.05 g/ml and water is (effectively) 1.0 g/ml. Recollect (from CHMY121) the %w/v refers to a solution with a certain mass of additive made up to 100 mL with the addition of (in this case) water; or % m/v= (grams of solute / 100 mL solution) ×100 The molar mass of Acetic Acid is 60.052 g/mol. What is the molarity of...
. Assume that vinegar is 5% acetic acid (by mass) at a density of 1.01 g mL-1. This means that 100 mL of vinegar you would have 5.05 g of acetic acid. Calculate the molar amounts of acetic acid and sodium bicarbonate that you will use in this experiment.
4. 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. 5. 50 ml...
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?
The reaction of sodium bicarbonate with acetic acid. If you have 0.03M sodium bicarbonate solution (you put 1g into 25 mL of seltzer water) and 0.03M vinegar solution (1.25mL into 25mL of seltzer water) how much carbon dioxide is generated in a 1:1, 2:1 and 1:2 ration of the reactants. Please show work
molarity of acid: 0.1435M volume:25ml 1. Use the molar mass and moles of acetic acid to determine the mass of the acetic acid in the 25.00-ml sample. 2. Calculate the mass/volume percentage (m/v %) by dividing the mass of acetic acid in grams by the volume of the vinegar sample in mL and multiplying by 100. 3. For the reaction of sodium hydroxide solution with a solution of hydrochloric acid: a. Write a balanced molecular equation for the reaction, including...

2.) Vinegar is an aqueous solution (homogenous mixture) of acetic acid and water laqueous 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...
