Answer:
115.95 grams of oxygen
Explanation:
The reaction equations is expressed as:
[tex]Ca(ClO_3)_2->CaCl_2+3O_2[/tex]
We know the molar mass of [tex]Ca(ClO_3)_2[/tex] as [tex]206.98\ g/mol[/tex] hence the number of moles in the 250g reaction is [tex]mol=\frac{250}{206.98}=1.20785 \ mol[/tex]
#Given the 1:3 ratio(to oxygen's moles), the number of moles of oxygen produced is:
[tex]O_2=1.20785\times3\\\\=3.62354 \ mol[/tex]
The molar mass of oxygen is 32g, therefore:
[tex]O_2_g=3.62354\times 32\\\\=115.95 \ grams[/tex]
Hence, 115.95 grams of oxygen are produced.
