a)
$C_6H_{12}O_6 \xrightarrow{t^o,xt} 2CO_2 + 2C_2H_5OH$
720 ml = 720 cm3
m dd glucozo = D.V = 720.1 = 720(gam)
m glucozo = 720.5% = 36(gam)
n glucozo = 36/180 = 0,2(mol)
Theo PTHH :
n C2H5OH = 2n glucozo = 0,4(mol)
m C2H5OH = 0,4.46 = 18,4(gam)
b)
V rượu = m/D = 18,4/0,8 = 23(ml)
Vậy :
Đr = 23/240 .100 = 9,583o
\(V_{C_2H_5OH}=\dfrac{1.1000.40}{100}=400\left(ml\right)\\ \rightarrow m_{C_2H_5OH\left(TT\right)}=400.0,8=320\left(g\right)\\ \rightarrow m_{C_2H_5OH\left(LT\right)}=\dfrac{320.100}{80}=400\left(g\right)\\ \rightarrow n_{C_2H_5OH\left(LT\right)}=\dfrac{400}{23}\left(mol\right)\)

20l = 20000ml
\(V_{C_2H_5OH}=\dfrac{23.20000}{100}=4600\left(ml\right)\\ m_{C_2H_5OH}=4600.0,8=3680\left(g\right)\\ n_{C_2H_5OH}=\dfrac{3680}{46}=80\left(mol\right)\)
