Answer:

115.97 grams

Explanation:

The reaction ensuing is expressed as:

$Ca(ClO_3)_2->CaCl_2+3O_2$

-The molar mass of $Ca(ClO_3)_2$ is given as $206.98\ gmol^{-1}$

#Calculate the moles of $Ca(ClO_3)_2$ in the reaction:

$Ca(ClO_3)_2_m=250/106.98\\\\=1.208 \ mol$

#The ratio of calcium chlorate to oxygen is 1:3,

$O_2 \ Moles=1.208\times 3\\\\=3.624 \ mol$

#Given the molar mass of oxygen per mole is 32 g, it’s weight in the reaction is calculated as:

$mass=3.624\times 32\\\\=115.97\ grams$

Hence, the mass of oxygen produced is 115.97 grams
