C6H12O6 =(дрожжи) = 2C2H5OH + 2CO2
C2H5OH + 3O2 =2 CO2 +3 H2O
6CO2 + 6H2O= (фотосинтез) = C6H12O6
243г
(C6H10O5)n + nH2O =H+= nC6H12O6
Сокращаем степень n и берем отношение 1:1
Ню(крахмала) : Ню(глюкозы) 1:1
Ню крахмала = 243/ 162= 1,5 моль
Ню глюкозы = 1,5 моль
m глюкозы = 1,5 * 180 = 270 гр
270г
C6H12O6 =дрожжи= 2C2H5OH + 2CO2
Ню(C6H12O6):ню(С2Н5ОН) = 1:2
Ню(С6Н12О6) = 270/180 = 1,5 моль
Ню(С2Н5ОН) = 3 моль
m(C2H5OH) = 3 * 46 = 138 г
138г
С2Н5ОН + 3О2 = 2СО2 +3Н2О
Ню(С2Н5ОН) : Ню(СО2) = 1:2
Ню(С2Н5ОН) = 138/46= 3 моль
Значит Ню(СО2) = 6моль
ответ Ню (СО2) = 6 моль
