PTHH: 2Na+Cl2\(\rightarrow\)2NaCl
nNaCl=\(\dfrac{8,775}{58.5}=0,15\left(mol\right)\)
nếu hiệu suất là 100% thì nNaCl=0,15/\(\dfrac{75}{100}\)=0,2(mol)
theo PTHH: nNa=nNaCl=0,2
\(\rightarrow\)mNa=0,2.23=4,6(g)
theo PTHH: nCl2=\(\dfrac{1}{2}\)nNaCl=0,1
\(\rightarrow\)VCl2=0,1.22,4=2,24(l)
2Na +Cl2 --> 2NaCl
nNaCl=8,775/58,5=0,15(mol)
theo PTHH : nCl2=1/2nNaCl=0,075(mol)
mà H=75% =>nCl2(thực tế)=0,075/75.100=0,1(mol)
=>mCl2=0,1.71=7,1(g)
nNa=nNaCl=0,15(mol)
mà H=75%=>nNa(thực tế )=0,15/75.100=0,2(mol)
=>mNa=0,2.23=4,6(g)
