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?

A

5 L

B

10 L

C

7 L

D

6 L

Text Solution

Verified by Experts

The correct Answer is:
A

`underset(1)(C_(3)H_(8))+underset(5)(5O_(2))rarrunderset(3)(3CO_(2))+underset("4")(4H_(2)O)underset("(volume)")`
So 1 volume or 1 litre of propane requires 5 volume or 5 litre of O2 to burn completely.
