1. Oblicz ile gramów glukozy należy użyć w celu otrzymania 500g roztworu etanolu o stężeniu 14%. Proszę o pomoc :)
mr=500g
Cp=14%
ms=Cp*mr/100%
ms=14*500/100
ms = 70g
mC6H12O6=180u
mC2H5OH=46u
C6H12O6 ---> 2C2H5OH + 2CO2
180g glukozy ---- 2*46g etanolu
xg glukozy ------- 70g etanolu
x = 136,96g glukozy
mr=500g Cp=14% ms=?
ms=mr*Cp/100%
ms=70g etanolu
C6H12O6-------->2C2H5OH+2CO2
x 70g
2mC2H5OH=92u
180u------x
92u-------70g
x=137g glukozy
