Problem data: m (mass of gasoline taken) = 18 kg.

Reference values: qb (specific heat of combustion of gasoline) = 46 MJ or 46 * 10 ^ 6 J / kg.

To calculate the heat released from combustion of 18 kg of gasoline, we use the formula: Q = qb * m.

Let’s calculate: Q = 46 * 10 ^ 6 * 18 = 828 * 10 ^ 6 J or 828 MJ.

Answer: When burning 18 kg of gasoline, 828 MJ of heat will be released.
