1. % p/p = peso soluto x 100
``````````````````
peso solución
preparar la solucion = n soluto + p solvente
p solución = 0.892 g + 80 g = 80.892 g
% p/p = 0.892 g x 100
``````````````
80.892 g
%p/p = 1.102 %
2. calcular peso soluto
p soluto = %p/p x p solución
``````````````````````````
100
p soluto = 5 g/g x 200 g
``````````````````````
100
p soluto = 10 g de KCl
3.
a) calcula p solucion = peso soluto x 100
````````````````
% p/p
p solución = 20 g x 100
````````
40 g/g
p solución = 50 g
b) calcular peso del solvente (agua)
p solución = p soluto + peso solvente
p solvente = 50 g - 20 g = 30 g de solvente (agua)
3. % p/v = p soluto x 100
````````````
v solución
%p/v = 10 g x 100
````````````
500 mL
% p/v = 2 %
5. calcular masa soluto
%p/p = p soluto x 100
````````````
p solución
p soluto = 1000 mL x 33 g/mL
````````````````````````````
100
P soluto = 330 g de CuSO4
``````````````````
