Air contain 20 % oxygen by volume. Calculate the theoretical volume of air. Which will be required for buring `100 cm^(3)` of propane completely. All volume are measured under same conditions of temperature and pressure.
A. `500 m^(3)`
B. `2500 m^(3)`
C. `100 m^(3)`
D. `5000 m^(3)`

Correct Answer - B
`C_(3)H_(8) + 5O_(2) rarr 3 CO_(2) + 4 H_(2)O`
`100 m^(3)`
`O_(2)` required for complete cumbustion of propane `= 500 m^(3)`
Amount of air `rArr x m^(3)`
`(20.)/(100) xx x = 500`
`x = 2500 m^(3)` air
