The chemical equation below shows the combustion of methane (CH4).

CH4+2O2--CO2+2H2O

The molar mass of oxygen gas (O2) is 32.00 g/mol. The molar mass of carbon dioxide (CO2) is 44.01 g/mol. What mass of CO2, in grams, will firm when 8.94 g O2 completely react?

a) 3.25

b) 6.15

c) 13.0

d) 53.0

CH₄ + 2O₂ - - - > CO₂ + 2H₂O

... 64g ... 44g ...

64g O₂ - - - 44g CO₂

8,94g O₂ - - - X

X = (44*8,94) / 64

X = 6,15g CO₂
