    Answer:

    approximately 15.1 grams.

    Explanation:

    The key to chemistry is to change everything to moles. Then when you have the answer in moles change the answer back to grams, liters, or whatever you want.

    change 25 grams of potassium chlorate to moles.

    calculate the gram molecular mass of potassium chlorate.

    Chlorate is Cl with 3 oxygens. ate = saturated. Chlorine has seven valance electrons when it is saturated six of these electrons are used by oxygen ( 2 electrons per oxygen) leaving only 1 electron.

    1 K x 39 grams/mole

    +1 Cl x 35.4 grams/ mole

    +3 O x 16 grams/ mole

    = 122.4 grams / mole Potassium Chlorate

    25

    122.4

    = moles.

    2.05 moles of Potassium Chlorate.

    There is a 1:1 mole ratio. 1 mole of Potassium Chlorate will produce 1 mole of Potassium Chloride.

    2.05 moles of Potassium Chlorate will produce 2.05 moles of Potassium Chloride.

    Find the gram molecular mass of Potassium Chloride.

    1 K x 39 = 39

    +1 Cl x 35.4 = 35.4

    = 74.4 grams / mole.

    2.05 moles x 74.4 grams/ mole = 15.2 grams
