M,Ca(OH)2= 74kg/kmol
M,C6H12O6= 180 kg/kmol
-calculez masa de glucoza cu puritatea 95%
p=mpx100/m,impur------> m,p=10x95/100kg= 9,5kg glucoza pura
-din ecuatiile reactiilor calculez masa de Ca(OH)2
C6H12O6---->2CO2 +2C2H5OH
CO2 + Ca(OH)2----.>CaCO3+H2O ori 2
i deduc
1kmol glucoza..........2kmol Ca(OH)2
180kg glucoza.............2x74kg
9,5kg....................................x..................................calculeaza !!!!
