Question

ayuda con este ejercicio de% v/v

Answer 1

% v/v  =  v soluto  x   100

            ``````````````````

            V solc.

v solc. = v soluto + v solvente

1. calcular v soluto

v soluto =  % v/v   x   v solc.

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

                             100

V soluto = 15 mL /mL  x  150 mL

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

                            100

V soluto = 22.5 mL

2. Calcular v solvente

v solvente = 150 mL - 22.5 mL

v solvente = 127.5 mL

 

Answer 2

Respuesta:

% v/v  =  v soluto  x   100

           ``````````````````

           V solc.

v solc. = v soluto + v solvente

1. calcular v soluto

v soluto =  % v/v   x   v solc.

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

                            100

V soluto = 15 mL /mL  x  150 mL

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

                           100

V soluto = 22.5 mL

2. Calcular v solvente

v solvente = 150 mL - 22.5 mL

v solvente = 127.5 mL
