Here, the temperature is kept constant, so we can consider the volume ratio the same as the mole ratio.
Now I want to know if my method of approach is correct or not.
Potassium hydroxide absorbs all the CO2, so we had 40 cm^3 of CO2, and therefore, X= 40
Now we can develop an equation
total volume - 20 cm^3 = volume of CO2 and H2O
(10 + 40 + y/4) - 20 = 40 + y/2
30 + y/4 = 40 + y/2
-10 = y/4
-40 = y
Now we can divide both by 10 to get:
x=4, y=-4
Therefore CxHy = C4H4
Now the problem is that why I got a negative 4?
Is my approach correct?
I have actually found a similar question answered somewhere and here is it:
My question is that why the water volume was not taken into account here? Your responses will be much appreciated
