Answer:

1.22 J/g.°C

Explanation:

Step 1: Given data

Mass of the metal (m): 17.5 g

Temperature increase (ΔT): 26.8 °C

Added energy (Q): 570.4 J

Step 2: Calculate the specific heat of the metal (c)

A metal absorbs heat and, as a consequence, its temperature increases. We can calculate its specific heat using the following expression.

c = Q / m × ΔT

c = 570.4 J / 17.5 g × 26.8 °C = 1.22 J/g.°C
