Question

20 ml of carbon monoxide is exploded with 30 ml of oxygen. Find the final volume of the gases in ml?

Answer 1

Given reaction:
2CO + O2 --->2CO2

2moles of CO + 1mole of O2 ----> 2moles of CO2

Moles of CO/Moles of O2  =2/1=2 -----------(1)

20 ml of CO  reacts with 10 ml of O2 to produce 20 ml of CO2
But 20 ml of O2 remains unreacted.It is limiting reagent here.
Volume of Final mixture=20ml of CO2+20ml of O2 
                                         =40ml 
The final volume of the gases is 40ml
