Enthalpy changes in chemical reactions 1 of 1 Pead through pages 1820 in your laboratory manual for inlormafion on how lo calaulate the enthaipy change in a solvtion. In a calorimety experiment 5.90 potassum hydrovide is distotved in 400.mL watur in a thermos fiask. The lemperatire increase in the solicon is 6.4 "O. The efiective mass of the olass in the thermot flatk (meai) is 0.040kg The heat capecity of the solusion (Cg) is 4.04klgg1K !. The heat capacity of the calorimeler (Cca) is 0.387kikgk1k. Remember to enter your answer using the spectiod eumber of sgififcant figures, but koep the artere number in your caiculator for use in further calculations Part A - Calculating me Caiculate the total mass of solution in Eilograms (m4) Give your antwer to four aignificent figures. Calculate the heat absorbed by the solution ( qsolution ) Give your answer to four significant figures. Calculate the heat absorbed by the glass in the calorimeter ( qcalorimeter) ). Give your answer to four significant figures. Calculate the total heat transferred for the reaction ( qtotal ) Glve your answer to four significant figures. Calculate the number of moles of KOH used in the experiment ( n ). Give your answer to four significant figures. Calculate the enthalpy change (AH) for the dissolution of one mole of KOH, that is, for the reaction: KOH(s)+K(aq)++OH(aq) Remember to consider the sign of H. Give your answer to 2 significant figures
