Calculate the mass, in grams, for each of the following using Table 3.9:
a. a gold (Au) sample that absorbs 225 J to change its temperature from 15.0 °C to 47.0 °C
b. an iron (Fe) object that loses 8.40 kJ when its temperature drops from 168.0 °C to 82.0 °C
c. a sample of aluminum (Al) that absorbs 8.80 kJ when heated from 12.5 °C to 26.8 °C
d. a sample of titanium (Ti) that loses 14 200 J when it cools from 185 °C to 42 °C
