Answer:
30 cc
Step-by-step explanation:
CH 4+2O2
→CO 2 +2H2O
Here, from the equation, we conclude that 2 c.c of O
2
is required to burn 1 cc of methane.
20 cc of methane is completely burnt using 50 cc of oxygen.
20 cc of methane will react with 40 c.c of oxygen to give 20 cc of carbon dioxide and liquid water. 10 c.c of oxygen will remain.
The volume of the gas left after cooling to room temperature is 10+20cc=30cc.
