Question

En un recipiente se disuelven 25 gramos de sal en 150 gramos de agua

Answer 1

m soluto = 25 g
m solvente = 150 g

m solucion = m soluto + m solvente
m solc. = 25 g + 150 g = 175 g

% m/m =  m soluto  x  100
               ``````````````
                 m solc

% m/m =  25 g  x  100
               ````````
               175 g

% m/m = 14.29

NOTA: SUPONGO QUE ES % LO QUE SE DEBE CALCULAR
