1.5 kg of fuel is burned on a natural gas grill during a barbecue. How much heat is released in kcal?

Can you please explain how you get your answer.

75 + √27
√(3*5^2) + √(3^3)
√3 * √(5^2) + √3 * √(3^2)
5√3 + 3√3 = 8√3 (ans)

  1. 75 + √27
    √(3*5^2) + √(3^3)
    √3 * √(5^2) + √3 * √(3^2)
    5√3 + 3√3 = 8√3 (ans)

  2. Natural gas (methane) = CH4
    MW = (12.0) + 4(1.01) = 16.04 g/mole
    (1500 g)(1mole/16.04 g)= 93.5 moles CH4

    Higher Heating Value of methane = 889 kJ/mole (from Wikipedia)
    (889 kJ/mole)((93.5 moles)(1 kcal/4.184 kJ)
    = 1.99 x 10^4 kcal
