QuestionCalculate the energy required to heat 368.0 g of aluminum from 0.3C0.3^{\circ} \mathrm{C} to 18.5C18.5^{\circ} \mathrm{C}. Assume the specific heat capacity of aluminum under these conditions is 0.903 J g1 K10.903 \mathrm{~J} \cdot \mathrm{~g}^{-1} \cdot \mathrm{~K}^{-1}. Be sure your answer has the correct number of significant digits.

Studdy Solution
Round the answer to the correct number of significant figures. The least number of significant figures in the given data is 4 (from 368.0g 368.0 \, \text{g} ).
q=6044.8416J6044Jq = 6044.8416 \, \mathrm{J} \approx 6044 \, \mathrm{J}
The energy required to heat the aluminum is:
6044J\boxed{6044 \, \mathrm{J}}
