\(a,n_{CO_2}=\dfrac{m_{CO_2}}{M_{CO_2}}=\dfrac{11}{44}=0,25\left(mol\right)\\ b,n_{H_2}=\dfrac{9.10^{23}}{6.10^{23}}=1,5\left(mol\right)\\ V_{H_2\left(đktc\right)}=1,5.22,4=33,6\left(l\right)\)
\(m_{CO_2}=12+16\cdot2=44\)
Số mol của CO2
\(n=\frac{m}{M}=\frac{11}{44}=0,25\)(mol)
Số mol của H2
\(n=\frac{sophantu}{6.10^{23}}=\frac{9.10^{23}}{6.10^{23}}=1,5\left(mol\right)\)
\(\Rightarrow\) VH2(đktc) =n.22,4=1,5.22,4=33,6(lít)
=> VH2(đktc) = 1,5 x 22,4 = 33,6 lít
a) nNaOH=20/40=0,5(mol)
nN2=1,12/22,4=0,05(mol)
nNH3= (0,6.1023)/(6.1023)=0,1(mol)
b) mAl2O3= 102.0,15= 15,3(g)
mSO2= nSO2 . M(SO2)= V(CO2,đktc)/22,4 . 64= 6,72/22,4. 64= 0,3. 64= 19,2(g)
mH2S= nH2S. M(H2S)= (0,6.1023)/(6.1023) . 34=0,1. 34 = 3,4(g)
c) V(CO2,đktc)=0,2.22.4=4,48(l)
nSO2=16/64=0,25(mol) -> V(SO2,đktc)=0,25.22,4=5,6(l)
nCH4=(2,1.1023)/(6.1023)=0,35(mol) -> V(CH4,đktc)=0,35.22,4=7,84(l)
+ \(M_{CO_2}=12+16.2=44\left(\dfrac{g}{mol}\right)\)
\(n_{CO_2}=\dfrac{m}{M}=\dfrac{11}{44}=0,25mol\)
+ \(n_{H_2}=\dfrac{9.10^{23}}{6.10^{23}}=1,5mol\)
\(V_{H_2\left(đktc\right)}=n.22,4=1,5.22,4=33,6\left(l\right)\)
\(a.\)
\(n_{CO_2}=\dfrac{11}{44}=0.25\left(mol\right)\)
\(b.\)
\(n_{H_2}=\dfrac{9\cdot10^{23}}{6\cdot10^{23}}=1.5\left(mol\right)\)
\(V_{H_2}=1.5\cdot22.4=33.6\left(l\right)\)
nSO2=m:M=6,4:64=0,1(mol)
VSO2=n.22,4=0,1.22,4=2,24(l)
nCO2=m:M=4,4:44=0,1(mol)
VCO2=n.22,4=0,1.22,4=2,24(l)
nH2=S:6.1023=1,2.1023:6.1023=0,2(mol)
VH2=n.22,4=0,2.22,4=4,48(l)
\(a.n_{SO_2}=\dfrac{m}{M}=\dfrac{6,4}{64}=0,1\left(mol\right)\\ n_{CO_2}=\dfrac{m}{M}=\dfrac{4,4}{44}=0,1\left(mol\right)\\ \Rightarrow n_{hh}=n_{SO_2}+n_{CO_2}=0,1+0,1=0,2\left(mol\right)\\ \Rightarrow V_{hh}=n.22,4=0,2.22,4=4,48\left(l\right)\)
\(n_{H_2}=\dfrac{1,2.10^{23}}{6.10^{23}}=0,2\left(mol\right)\Rightarrow V_{H_2}=n.22,4=0,2.22,4=4,48\left(l\right)\)
