Question

Se mezcla 10mL de alcohol en 150mL de agua. ¿Cuál es el porcentaje de agua y alcohol?​

Answer 1

Respuesta:

1. %v/v = v soluto x 100

````````````

v solc.

v solc. = 10 mL + 150 mL = 160 mL

%v/v = 10 mL x 100

`````````````

160 mL

%v/v = 6.25 %V/V de alcohol

% v/v = 150 mL x 100

``````````

160 mL

%v/v = 93.75 %v/v de agua

2. %m/v = masa soluto x 100

```````````````````

volumen solución

% m/v = 16 g x 100

````````````

75 mL

%m/v = 21.33 %g/mL

3. % v/v = v soluto x 100

```````````

v solc.

v solc = V soluto + v solvente

v solc. = 1 mL + 40 mL = 41 mL

% v/v = 1 mL x 100

`````````

41 mL

%v/v = 2.439 %
