Answer:
...the which represents the complete combustion of methane...
We combust a mass of 2.60⋅mg of methane with respect to methane...a molar quantity of...
2.60×10−3⋅g16.04⋅g⋅mol−1=1.62×10−4⋅mol...
...and thus we get TWICE this molar quantity of water....i.e. a mass of...2×1.62×10−4⋅mol×18.01⋅g⋅mol−1=5.84⋅mg.
And if we combust a molar quantity of 1.62×10−4⋅mol, the equation dicates that we combust TWICE this molar quantity of dioxygen....a mass of....
2×1.62×10−4⋅mol×32.00⋅g⋅mol−1=0.0104⋅g
