A block of aluminum with a volume of 98.5 cm3 absorbs 67.4 J of heat. If its initial temperature was 32.5°C, what is its final temperature? (density of aluminum = 2.70g/cm3)

Use density to convert volume Al to mass. m = volume x density.
J = mass Al x sp.h. Al x (Tfinal-Tinitial). Subsitute and solve for Tf.
