A compound `(C_(x)H_(y)O_(z))` on analysis gave the following percentage composition by weight :
Hydrogen = 9.09, Oxygen = 36.36, Carbon = 54.55
Its vapour denstiy is 44. What is the value of `(y+z-x)` ?

`{:(,%" mass",,"mole"),(H,9.09,,(9.09)/(1)=9.09),(O,36.36,,(36.36)/(16)=2.2725),(C,54.55,,(54.55)/(12)=4.54),(H," "O,," "C),((9.09)/(2.27)=4,(2.27)/(2.27)=1,,(4.54)/(2.27)=2):}`
`therefore" "C_(2)H_(4)O " "EFM = 44`
`MFM=2 xx 44 = 88`
`therefore " "MF = (C_(2)H_(4)O_(2))" or "C_(4)H_(8)O_(2)`
