  • Question 7/10
    4 / -1

    Dioxygen difluoride (O2F2) is a highly oxidising and unstable liquid. At 300 K it decomposes back to oxygen and fluorine, which are both gases at this temperature. The equation for the reaction is given below. 0.1 g of O2F2 was left for 24 hours and the 24.9 ml of gas mixture evolved was collected at 300 K and 100 kPa. What % by mass of dioxygen difluride has decomposed by this time?
    O2F2(l) → O2(g) + F2(g)
