Oblicz ile cm3 wody odparowano z 400g 20% roztworu jeśli uzyskano roztwór 25%
Dam Naj :)
Cp=ms/mr*100% ; mr=mroz+ms
20%=ms/400*100%
ms=80g
mroz=400-80=320g
25%=80/(mroz+80)*100%
0,25=80/(mroz+80)
mroz+80=320
mroz=240g
320-240=80g - tyle wody odparowano
1000g - 1000cm3
80g - x
x=1000*80/1000
x=80cm3
