a. 0.73

Explanation:

Given data

Added heat (Q) : 38.5 J Change in the temperature (ΔT) : 3.0°C Mass of the metal (m) : 17.5 g Specific heat of the metal (c) : ?

We can determine the specific heat of the metal using the following expression.

Q = c * m * ΔT

c = Q / m * ΔT

c = 38.5 J / 17.5 g * 3.0°C

c = 0.73 J/g.°C
