\(n_{KClO_3\left(bd\right)}=\dfrac{55,125}{122,5}=0,45\left(mol\right)\)
=> \(n_{KClO_3\left(pư\right)}=\dfrac{0,45.85}{100}=0,3825\left(mol\right)\)
PTHH: 2KClO3 --to,MnO2--> 2KCl + 3O2
0,3825------------------->0,57375
=> \(V_{O_2}=0,57375.22,4=12,852\left(l\right)\)
2KClO3-to>2KCl+3O2
0,45---------------------0,675 mol
n KClO3=\(\dfrac{55,125}{122,5}\)=0,45 mol
=>H=85%
=>VO2=0,675.22,4.\(\dfrac{85}{100}\)=12,852l
