please solve these correctly thanks

A 0.375g sample of solid LBrH2O(s) is dissolved in 194mL of water in a colfee cup calorimetec. Once all of the Libr. H2O(s) is disolved in the water, the final temperature of the solution is found to be 35.91C. If the initial temperature of the water in the calorimeter was 22.11C, calculate the calorimeter constant (in 1/K ) for the coffee cup calorimeter. Report your answer to three significant figures. The heat of scivation of LBCH2O(s) is 23.26kJ/ mol. A pare sample of pure ethyoxyethene (C4P4O) is cembusted in a bomb calorimeter. If the combustan of 0.401g of ethyoxyethene results in a rise in temperature frem 13.53C to 19.35C, what is the heat capacity (in ky/K) of the calonmeter? fleport your answer to three signticant figures. The heot of combustion for ethyoxyethene is 2577.30kJ/mol
