Explanation Given info: The mass of sample cookies is 10 g , the mass of aluminum container is 0.615 kg , the mass of water is 2 kg , the mass of aluminum calorimeter cup is 0 .524 kg , the initial temperature is 15 ° C and the final temperature is 36 ° C . The principle of calorimetric is written as, Heat lost = Heat gained The heat gained is calculated as, Heat gained = + ( m Al c Al ( T f − T i ) + m w c w ( T f − T i ) + m C c Al ( T f − T i ) ) = ( T f − T i ) ( m Al c Al + m w c w + m C c Al ) m Al is the mass of aluminum container. • m w is the mass of water. • m C is the mass of calorimeter. • c Al is the specific heat capacity of aluminum. • c w is the specific heat capacity of water. • T f is the final temperature... To determine Section 2: The energy content of 100 g Karen’s fudge cookies.
