\(n_{KClO_3}=\dfrac{36,75}{122,5}=0,3\left(mol\right)\)
PT: \(2KClO_3\underrightarrow{t^o}2KCl+3O_2\)
Theo PT: \(n_{O_2\left(LT\right)}=\dfrac{3}{2}n_{KClO_3}=0,45\left(mol\right)\)
\(\Rightarrow V_{O_2\left(LT\right)}=0,45.24,79=11,1555\left(l\right)\)
\(\Rightarrow H=\dfrac{6,69}{11,1555}.100\%\approx59,97\%\)
\(n_{KClO_3}=\dfrac{36,75}{122,5}=0,3\left(mol\right)\)
\(n_{O_2}=\dfrac{6,69}{24,79}=0,27\left(mol\right)\)
PTHH :
\(2KClO_3\rightarrow\left(t^o\right)2KCl+3O_2\)
0,3 0,3 0,45
\(H=\dfrac{0,27}{0,45}.100\%=60\%\)
