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)%

The cube has a mass of 72.9 g.<br><br> What is its density in g/cm3? <br><br> What substance is it?
sashaice [31]
If the cube is 3 cm on each side, then it has a volume of 27 cm^3 (3 x 3 x 3). Density is mass divided by volume, so its density is 72.9/27 = 2.7 g/cm^3. 

<span>Going by the density, the cube is made of Aluminium - density is a fairly unique quantity</span>

How is it that when a salt sample dissolves in water, the delta S for the process is positive?
Bess [88]

Answer:-

Water is highly ordered. In water each oxygen atom is connected to others around it through hydrogen bonding via bridging hydrogen atoms. When a salt like NaCl is dissolved, some of these Hydrogen bonds break.

When a salt like NaCl dissolves in water, the NaCl breaks in to ions Na+ and Cl-.

The water molecules now surround these ions.

The slightly negative oxygen end of water molecule gets near the Na+, while the slightly positive Hydrogen of water molecule gets near the Cl-.

So before salt sample dissolve, the water molecules were highly ordered due to hydrogen bonding. Now after salt dissolve there is a decrease in order and thus an increase in disorder of the water molecules.

Due to increase in disorder, entropy which is a measure of disorder increases. Since entropy increases, delta S for the process is positive.
