Sagot :
The mass of CH₄ that is consumed is 10.598 g.
What is enthalpy?
The enthalpy of a system is defined as the sum of the internal energy of a system and the energy that is produced due to its pressure and volume.
It is given by
H = U+PV
The following reaction takes place during the combustion of CH₄
[tex]CH_4(g)+2O_2(g)\rightarrow CO_2(g)+2H_2O(g)[/tex]
Energy evolved during the combustion, E = 587.9 kJ
Enthalpy of combustion of methane, ∆H = 890.3 kJ
[tex]No of moles of CH_4 =\frac{energy evolved}{enthalpy of combustion}[/tex]
= 587.9 /890
Mass of CH₄ that is consumed = no of moles × molar mass of CH₄
= 587.9 /890 × 16
= 10.598 g
The mass of CH₄ which is consumed is 10.598 g
