To calculate the mass of burnt peat, we apply the formula: Q = qt * m, whence m = Q / qt.
Constants and variables: Q – released heat (Q = 132 kJ = 132 * 10 ^ 3 J); qt is the specific heat of combustion of peat (qt = 1.4 * 10 ^ 7 J / kg).
Let’s make a calculation: m = Q / qt = 132 * 10 ^ 3 / (1.4 * 10 ^ 7) = 0.00943 kg or 9.43 g.
Answer: 9.43 grams of peat burned out.
