One mole methane is completly burned in xcess oxygen. If 8.90x10^3kj of heat are given off from theis reaction, calculate the heat given off for 1.44g of methane.

  • Chemistry -

    CH4 + 2O2 ==> CO2 + 2H2O
    8.90 x 10^3 kJ given off for 1 mole(16 g) CH4.
    1.44 g will give off
    8.90 x 10^3 kJ x (1.44/16) = ??
