If a block of gold requires 1.42 kJ of energy to raise the temperature from 120.0°C to 240.0°C,what is the mass of the block? The specific heat capacity of gold is 0.129 J/g-K.

Question

The correct answer is A.Explanation:The mass of the block can be calculated using the formula:Q = mcΔTwhere Q is the energy required to raise the temperature, m is the mass of the block, c is the specific heat capacity of gold, and ΔT is the change in temperature.Substituting the given values into the formula, we get:1.42 kJ = m * 0.129 J/g-K * (240.0°C - 120.0°C)1.42 kJ = m * 0.129 J/g-K * 120°Cm = 1.42 kJ / (0.129 J/g-K * 120°C)m = 92.0 gTherefore, the mass of the block is 92.0 g.
