Consider the following reaction
CH4 + 2 O2 ===> CO2 + 2 H2O
27.3 grams of CH4 will produce How many Grams of H2O

Molecular weight of CH4 = 12+4 = 16
of 2 O2 = 2*(16*2) = 64
of 2H2O = 2*(16+1+1) = 2*18 = 36
So 16 grams of CH4 will produce 36 grams of H2O
27.3 will produce???
Do the math:)

27.3 grams of CH4 = 27.3/16 moles of CH4 so 2 times that number of moles of H2O will be produced giving
(27.3/16)(2)(18) = 61.4 grams of H2O

27.3gCH4 x 1mollCH4/16gH4 x 2molH2O/1molCH4 x 18gH2O/1molH2O = (27.3)(2)(18)/(16) = 61.4 g H2O
