Question

Mass of co2 and h2o formed on complete combustion of 24g if methane

Answer 1

Formula of methane= CH4 ; molecular mass of CH4= 16 g, CO2=44 g, H2O=18 g  

CH4 + O2   CO2 + H2O  

According to the equation,

16 g of CH4 produces 44 g CO2

Thus, 24 g of CH4 produces (44/16) ×24=66 g of carbon dioxide

Similarly, 16 g of CH4 produces 18 g H2O

Thus, 24 g of CH4 produces (18/16) ×24=27 g of water
