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 %
