<u>Answer:</u>
Vinegar is made from the fermentation of dilute alcoholic liquids into acetic acid.
<u>Explanation:</u>
Vinegar is a sour tasting liquid which is produced by the fermentation of dilute alcoholic liquids such as cider, wine and beer.
It is a solution of acetic acid which is more formally also known as ethanoic acid.
The concentration of acetic acid in vinegar is variable as it is used for different purposes with different concentrations.
Answer:
The concentration of the copper(II) sulfate solution is 0.99 M
Explanation:
Step 1: Data given
Mass of copper(II) sulfate = 79 grams
Volume of the flask = 500 mL
Molar mass copper(II) sulfate = 159.61 g/mol
Step 2: Calculate moles copper(II) sulfate
Moles CuSO4 = Mass CuSO4 / molar mass CuSO4
Moles CuSO4 = 79.0 grams / 159.61 g/mol
Moles CuSO4 = 0.495 moles
Step 3: Calculate concentration
Concentration CuSO4 = moles / volume
Concentration CuSO4 = 0.495 moles / 0.5 L
Concentration = 0.99 M
The concentration of the copper(II) sulfate solution is 0.99 M
