When burning gasoline, 2.3 * 10 ^ 10 J of energy was released. Determine the mass of gasoline burned.

When burning gasoline, 2.3 * 10 ^ 10 J of energy was released. Determine the mass of gasoline burned. The specific heat of combustion of gasoline is 4.6 * 10 ^ 7 J / kg.

These problems: Q (the amount of heat released during the combustion of gasoline) = 2.3 * 10 ^ 9 J.

Reference values: according to the condition q (specific heat of combustion of gasoline) = 4.6 * 10 ^ 7 J / kg.

You can determine the mass of burned gasoline by the formula: m = Q / q.

Let’s make a calculation: m = 2.3 * 10 ^ 9 / (4.6 * 10 ^ 7) = 50 kg.

Answer: To obtain 2.3 * 10 ^ 9 J of thermal energy, 50 kilograms of gasoline were burned.
