when 22.4 L of `C_(4) H_(8) ` at STP is burnt completely , 89.6 L of `CO_(2) ` gas at STP and 72 g water are Produced . The volume of the oxygen gas at STP consumed in the reaction is closest to

Options

A. 89.6L
B. 112 L
C. 134.4L
D. 22.4L

Answer

C

Explanation

`C_(4) H_(8) (g) +6O(g) to 4CO_(2)(g) + 4H_(2) O(g) `
`{:((22.4L)/(22.4), 89.6L,72 gm),(=1 "mole" ,=4"mole" ,="4mole"):} `
` n_(o_(2))=6xx22.4=134.4L`
