Question: When 2.25 mg of anthracene, CI4HlO(s), was burned in a bomb calorimeter the temperature raised by 1.35 K. Calculate the calorimeter constant. By how much

When 2.25 mg of anthracene, CI4HlO(s), was burned in a bomb calorimeter the temperature raised by 1.35 K. Calculate the calorimeter constant. By how much will the temperature rise when 135 mg of phenol, C6HsOH(s), is burned in the calorimeter under the same conditions? (∆.c H (C14H1O, s) =-7061 k) mol-1)
