\(n_{NaCl\left(lt\right)}=\dfrac{8.775}{58.5}=0.15\left(mol\right)\)
\(2Na+Cl_2\underrightarrow{^{t^0}}2NaCl\)
\(0.15..................0.15\)
\(m_{Na\left(tt\right)}=\dfrac{0.15\cdot23}{75\%}=4.6\left(g\right)\)
nNaCl=\(\dfrac{8,775}{58,5}=0,15\left(mol\right)\)
PTHH 2Na+Cl2---->2NaCl
---------0,15------------0,15
=>nNa(tt)=\(\dfrac{0,15}{75}.100=0,2\left(mol\right)\)
=>mNa(tt)=0,2.23=4,6(g)
