What volume of oxygen gas (O(2)) measure...

What volume of oxygen gas `(O_(2))` measured at `0^(@)C` and 1 atm is needed to burn completely `1 L` of propane gas `(C_(3)H_(8))` measured under the same condition?

Text Solution

Verified by Experts

The correct Answer is:
B
`underset("at NTP")underset(22.4 L)(C_(3)H_(8)(g)) + underset(5 xx 22.4 L "at NTP")(5O_(2)(g)) to 3CO_(2)(g) + 4H_(2)O(l)`
22.4 L of `C_(3)H_(8)` at NTP require `O_(2) = 5 xx 22.4` L
1 L of `C_(3)H_(8)` at NTP will require `O_(2)`
`=(5 xx 22.4)/22.4`L at N.T.P.
= 5L
