Moles of NaOH used in titration mole NaOH Moles of HC2H3O2 neutralized by NaOH mole HC2H3O2 Molarity of HC2H3O2 M HC2H3O2 Grams
Marta_Voda [28]

For the given picture:

Moles of NaOH = A × 0.04183 moles

Moles of HC2H3O2 neutralized = (A × 0.04183) moles

Mass of HC2H3O2 = (2.0598 × A)g

Percent (m/v) HC2H3O2 in vinegar = (411.96 × A)%

<h3>What is molarity?</h3>

A mole is the unit of measurement used for chemicals, hence the term "molarity". Molarity, also known as solution molarity, is a technique for calculating the amount of a substance in a particular chemical solution.

Let molarity of NaOH be A from picture, volume of vinegar used is 5ml.

Now, average volume of NaOH used for titration = 0.04183 L (as per picture)

Molarity of NaOH = A

So,

(C7) Moles of NaOH = A × 0.04183

as 1 mol NaOH neutralizes 1 mol CH3COOH

(A × 0.04183) moles will neutralize (M × 0.04183) moles CH3COOH

(C8) moles of HC2H3O2 neutralized = (A × 0.04183)

Molar mass of HC2H3O2 is 60 gm/mol

So mass of (M × 0.04183) moles is (A × 0.04183 × 60) = (2.0598 × A)

(C9) Grams HC2H3O2 = (2.0598 × A)

Now volume of (vinegar+acetic acid) that was titrated = 5ml or 0.005 L

Now, M₁V₁ = M₂V₂

where,

M₁ = A

V₁ = 0.04183L

M₂ = ?

V₂ = 0.005L

put all values, value of V must be in liters

M₂ = (0.04183 × A)/0.005 = 8.366A Molar

(C10) molarity of HC2H3O2 = 8.366A Molar

Now grams of HC2H3O2 is taken from C9 and volume of vinegar is 0.005L

(C11)so mass of acetic acid/volume of vinegar(m/v)

= [(2.0598 × A)/0.005]

= (411.96 × A)%

Studentka2010 [4]

Answer: C. Oxygen Gas

Explanation: When Hydrogen Gas and Oxygen Gas combine together it forms water correct. When you have an excess amount of another it stays neutral because it has no other molecule to react with.

Can someone help me out with why is the outer core of Earth is important in you’re own words?! A mini paragraph plsss
Helen [10]

Answer:

the outer core is important because the outer core is responsible for earth's magnetic field which protects earth from harmful particles that comes from sun and also contains some natural metal like nikle and iron.

is this much paragraph enough comment down below..

hope this helps you ☺️☺️
