Question

CH4 + 2O2 –> CO2 + 2H2O

Given the equation above, how many grams of water would result from the complete combustion of 1.47 grams of methane (CH4)?

Answer 1

3.3075 gm of H2O

Equation is:-

CH4 + 2O2 = CO2 + 2H2O

According to molar weights :

16 gm CH4 + 64 gm O2 = 44 gm CO2 + 36 gm H2O

Since 16 gm CH4 produce 36 gm H2O

Hence 2.5 gmCH4 produce 36×2.5/16 gm H2O

=> 5.265 gm of H2O

Hope it helps

Thanks.
