Question

100 mL of C2H6 burning with O2 to give CO2 and H20, then volume of O2 at STP required is mL.​

Answer 1

Answer:

C2H2+5/2O2———->2CO2+H2O

So 22400ml of C2H2 need=2.5 mole O2

ie 22400 ml of C2H2 need=22400 x 2.5 ml O2

100 ml of C2H2need=22400 x 2.5x100/22400

= 2 .5 x 100=250 ml of Oxygen.
