Question

An unknown mass of Al absorbs 187.9 J of heat and increases its temperature from 23.5 °C to 35.6 °C. What is the mass of the
aluminum?
Where:
Specific Heat of Aluminum is = 0.900 J/gºC

Answer 1

Answer:

mass = 17.2 grams

Explanation:

q = mcΔT => m = q/cΔT = 187j / (0.90j/g°C)(35.6°C - 23.5°C) = 17.2g
