Respuesta:
16,7 mL
Explicación:
Paso 1: Información provista
- Concentración inicial (C₁): 6%
- Concentración final (C₂): 0,5%
- Volumen final (V₂): 200 mL
Paso 2: Calcular el volumen de la solución concentrada
Queremos preparar una solución diluida de hipoclorito de sodio a partir de una concentrada. Podemos calcular el volumen inicial que debemos tomar usando la regla de dilución.
C₁ × V₁ = C₂ × V₂
V₁ = C₂ × V₂ / C₁
V₁ = 0,5% × 200 mL / 6% = 16,7 mL
<span>Eventually the increase in water may cause the blood cells to burst (cytolysis.) In a hypertonic solution, the concentration of dissolved solutes is greater than that of the cell. ... If the salt solution outside is 20% salt, then the water concentration is 80%.
The red blood cells will shrink in size due to osmotic-like pressure differences until it reaches a "favorable" size.</span>
Answer:
The answer is
<h2>0.56 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%20%5C%5C%20)
From the question
mass of liquid = 0.165 g
Next we change the volume from L to mL using the conversion
1 L = 1000 mL
We have
If 1 L = 1000 mL
Then 0.000295 l = 1000 × 0.000295
volume = 0.295 mL
The density is
![density = \frac{0.165}{0.295} \\ = 0.55932203...](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B0.165%7D%7B0.295%7D%20%20%5C%5C%20%20%3D%200.55932203...)
We have the final answer as
<h3>0.56 g/mL</h3>
