Cp=35/150+35 * 100% = 18,92%

10dm3= 10 000 cm3
m = 10 000cm3 * 0,79g/cm3 = 7 900g
1kg = 1000g
Cp=1 000g /7 900g+1 000g * 100% = 11,24%

20%=x/400 * 100% | * 400/100%
80= x
x=ms
mr-ms=mw (masa wody)
400-80= 320g wody
8.28
10%=x/200 * 100% |x200/100%
x= 20g
zakładamy że :
w 100g - 95g NaOH
w x g - 20g NaOH
x= 21g

200g *3% = 6g
200g - 6g = 194g ZnCl2
Cp=194/2000+200 * 100% = 8,82 %
Liczę na Naj ;) Jeśli coś niejasne, proszę pytać :)
