Calcula que cantidad de soluto y de disolvente hay en 200 mL de una disolución al 20% v / v?

% v / v = v soluto x 100 ```````````` v solc.

V soluto = %v / v x v solc.

```````````````````` 100

v soluto = 20 mL / mL x 200 mL `````````````````````````````` 100

V soluto = 40 mL

V SOLUCIÓN = V soluto + v solvente

v solvente = v soluciçon - v soluto

v solvente = 200 mL - 40 mL = 160 mL DE SOLVENTE.
