Answer:
[tex]1\ \text{gram}[/tex]
Explanation:
Mass of [tex]KClO_3[/tex] = 25.55 gram
Molar mass of [tex]KClO_3[/tex] = 122.5 g/mol
Molar mass of [tex]O_2[/tex] = 32.2 g/mol
The decomposition reaction is
[tex]3KClO_3\rightarrow 2KCl+3O_2[/tex]
The mass of [tex]O_2[/tex] produced would be
[tex]2.5\times \dfrac{1}{122.5}\times \dfrac{3}{2}\times 32=0.9795\approx 1\ \text{gram}[/tex]
The mass of [tex]O_2[/tex] produced is [tex]1\ \text{gram}[/tex].
