A chemist carefully measures the amount of heat needed to raise the temperature of a 1.51 kg sample of a pure substance from 46.7 °C to 58.5 °C. The experiment shows that 74.5 kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 3 significant digits.

Transcribed Image Text:**Thermochemistry: Calculating Specific Heat Capacity**
A chemist carefully measures the amount of heat needed to raise the temperature of a 1.51 kg sample of a pure substance from 46.7 °C to 58.5 °C. The experiment shows that 74.5 kJ of heat are needed. What can the chemist report for the specific heat capacity of the substance? Round your answer to 3 significant digits.
**Specific Heat Capacity (C) Formula:**
\( C = \frac{q}{m \Delta T} \)
Where:
- \( q \) = heat added (in Joules)
- \( m \) = mass of the substance (in kilograms)
- \( \Delta T \) = change in temperature (in Celsius or Kelvin)
The text box indicates that the answer should be provided in the unit J·g\(^{-1}\)·K\(^{-1}\).
