Twenty millilitres of a gaseous hydrocarbon required 400 ml of iar for complete cumbustion. The air contains `20%` by explosion and cooling was found to be 380 ml.
Q. Volume of `O_2` used is:

A

70 ml

B

75 ml

C

80 ml

D

85 ml

Text Solution

Verified by Experts

The correct Answer is:
C
Volume of `O_2` used `=(400xx20)/(100)=80ml`
