PTHH: 2KClO3 --to--> 2KCl + 3O2
\(n_{KCl}=\dfrac{45}{74,5}=\dfrac{90}{149}\left(mol\right)\)
PTHH: 2KClO3 --to--> 2KCl + 3O2
___________________\(\dfrac{90}{149}\)--> \(\dfrac{135}{149}\)___(mol)
=> mO2 = \(\dfrac{135}{149}.32\approx29\left(g\right)\)

\(2^x.3^{x+4}=104976\)
\(\Rightarrow2^x.3^x.3^4=104976\)
\(\Leftrightarrow\left(2^x.3^x\right).81=104976\)
\(\Leftrightarrow\left(2.3\right)^x=\frac{104976}{81}\)
\(\Leftrightarrow6^x=1296\)
\(\Leftrightarrow6^x=6^4\)
\(\text{Vậy }x=4\)
