How many moles of methane are required to produce 22g CO2(g) after combustion?
0.5
0.35
1.5
1.25
According to the chemical equation,
CH4 (g) + 2O2 (g) → CO2(g) + 2H2O (g)
44g CO2 (g) is obtained from 16 g CH4 (g).
Number of moles of CO2 (g)=0.5 mol
Hence, 0.5 mol CO2 (g) would be obtained from 0.5 mol CH4 (g) or 0.5 mol of CH4 (g) would be required to produce 22 g CO2(g).
Therefore, Option(1) is correct.
