The equation of a simulated photosynthesis reaction is represented by 6CO2(g) + 6H2O (g) -> C6H12O6(s) + 6O2(g) At 31 degree celcius, tje following equilibrium concentration were found [H2O] = 7.91X10^-2M [CO2]= 9.30X10^-1M [O2]= 2.40X10^-3M Determine the initial mass of CO2 involved in the above reaction

  1. I would do it this way with y = initial concentration of CO2 and z the initial concentration of H2O
    ..............................6CO2(g) + 6H2O (g) -> C6H12O6(s) + 6O2(g)
    I................................y.................z..................solid.................0
    C.............................-6x............-6x..................solid...............+6x
    E............................y-6x...........z-6x................solid................+6x

    Now you know y-6x = 0.930 M and 6x = 0.0024 M
    Solve for y

  2. Thank you Dr, i have did the same method as you ๐Ÿ˜Š. But i only managed to get the concentration of CO2 , instead of mass of CO2. Do you think the question lack of information if we are required to find mass of CO2?
