Question

calcular el % m/v de una solución que contiene 28,2 g de cloruro de potasio en 1,5 litros de solución

Answer 1

calcular el % m/v de una solución que contiene 28,2 g de cloruro de potasio en 1,5 litros de solución

% m/v =  masa soluto   x  100

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

                    v solc.

calcular % m/v

V = 1.5 x 1000

V = 1500 mL

% m/v = ( 28.2 g / 1500 mL)  x  100

% m/v = 1.88 %g/mL

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

% m/v = ( 28.2 g / 1.5 L)  x  100

% m/v = 1880 %g/L
