Answer:

18.1% V/V

Explanation:

El porcentaje volumen/volumen (%v/v) es una unidad de concentración en química definida como la relación entre volumen de soluto y volumen total de la solución (En las mismas unidades ambos volúmenes) por cien. La fórmula es:

% V/V = Volumen soluto / Volumen solución × 100

Analizando el problema, el soluto es ácido nítrico (Menor cantidad) y el solvente es el agua.

Recordando, el volumen de la solución es igual al volumen del soluto + el volumen del solvente. Así:

% V/V = 45.2mL soluto / (45.2mL + 205mL) × 100 =

<em>18.1% V/V</em> es la concentración de la solución.

$F^{-}$ is most abundant and 6310 times more than HF.

<h3>What is a strong and weak acid?</h3>

When an acid is dissolved in water, all of its molecules disintegrate, making the acid powerful.

When an acid is dissolved in water, only a small number of its molecules disintegrate, making the acid weak. Strong acids have a lower pH than weak acids.

The powerful acids include perchloric acid, chloric acid, nitric acid, sulfuric acid, hydrobromic acid, and hydroiodic acid.

Given:

Pka=3..2

pH=7

Let the volume be 1 liter

[HF]=01 M

$pH=pka+log \frac{F^{-}}{HF} \\\\7=3.2+log\frac{F^{-}}{HF} \\3.8=log\frac{F^{-}}{HF}\\ \frac{F^{-}}{0.1}=10^{3.8} \\F^{-}=630.95 M$

Now,

$\frac{F^{-}}{HF}=\frac{630.95}{0.1}\\ =6309.57$

F-:HF= 6309.57:1

Therefore, the most abundant is $F^{-}$ and has 6310 times more than HF is $F^{-}$ .

The order would be coefficient, law of conservation of mass, products, and reactants respectively.

<h3>Word matching</h3>

The number written in front of a chemical symbol in an equation is called a coefficient.

The total mass of a system being unchanged is known as the law of conservation of mass

The substances made in chemical reactions are called products.

The starting materials in chemical reactions are called reactants.
