make certain you use for water specific heat J/ kg units. watch units.
A 1.35-gram sample of compound X (of MW
88.0 g/mol) was burned in a bomb calorimeter
containing 1700 g of water. A temperature
rise of 0.96◦C was observed. ∆Erxn for this reaction
is −475 kJ/mol of X. What is the heat
capacity of the calorimeter hardware (not the
water)?
Answer in units of J/
â—¦C.
