Given the balanced equation:

Monica [59]

Answer: 7.88375g

Explanation:

Here is the dimensional analysis table

7g O2 | 1 mol O2 | 2 mol H2O | 18.02 g H2O

| 32 g O2 | 1 mol O2 | 1 mol H2O

You use grams to convert to moles of O2, then use that to find grams of H20

A 28. 0 ml sample of vinegar, which is an aqueous solution of acetic acid, ch3cooh, requires 21. 5 ml of 0. 550 m naoh to reach

Fittoniya [83]

Concentration of vinegar sample of 28mL which requires 21. 5 ml of 0.550 M NaOH to reach the endpoint in a titration is 0.42M.

<h3>How do we calculate the concentration of Vinegar?</h3>

Concentration of vinegar in the titration method will be used by using the below equation:

M₁V₁ = M₂V₂,

M₁ & V₁ are the molarity and volume of acetic acid.
M₂ & V₂ are the molarity and volume of vinegar sample.

By putting values on above equation from the question, we get

M₂ = (0.55M)(21.5mL) / (28mL) = 0.42 M

Hence, required concentration of vinegar is 0.42M.
