  • @alanmez5062
    @alanmez5062 3 ปีที่แล้ว +32

    Question 1 : Calculation
    0.01186 = 1186 × 10^-5
    so 1 /1186 × 10^-5
    i.e. 100000/1186
    50000 / 593 ( After dividing num and deno by 2)
    Now, 593 can be also written as 590..to make calculation simple
    Therefore 50000/590 -> 5000/59 = 84.74
    Hope you could understand !

      Let the volume of ozone be x ml so it is equal to x/22400l
      So volume of oxygen=600-x/22400 l
      Now weight of o2=32(600-x)/22400
      Weight of o3=48(x/22400)
