What volume of oxygen at s.t.p is required to burn completely 7.5 dm3 of methane according to the following equation?
CH4 g + 202 g → CO2 g + H2Og
3.75 dm3
7.59 dm3

30.0dm3
Correct answer is C
1 mole of methane reacts with 2 moles of oxygen
1 vol of methane reacts with 2 vol of oxygen
: 7.5 vol of methane will yield 15 vol of oxygen in dm3
