    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
