0.9 gm of a volatile solid organic compound (molecular weight =90) containing carbon, hydrogen and oxygen was heated with 224 ml of oxygen at 1 atm and `0^(@)` c. After combustion, the total volume of gases was 560 ml at same T and P. On treatment with KOH, the volume decreased to 112ml. Determine the value of x+y+z if molecular formula of organic compound is `C_(x)H_(y)O_(z).`
