  1. 1. Write the equation and balance it.
    2. Convert what you have (KClO3) to moles. # moles = grams/molar mass.
    3. Using the coefficient in the balanced equation, convert mole KClO3 to moles O2.
    4. Now use PV = nRT to convert moles O2 at STP to liters of O2 at the other conditions.
    Post your work if you get stuck.
