Show calculations was determined for the dissolving determined fo following Part of the Ex cedure in this experiment. the following table for Trial (See Report Sheet.) for de the e solution of KBr. py of 5.00 Part 2 1. Mass of salt (g) 2. Moles of salt (mol 25.0 5, Mass of water (g) 6. Initial temperature of water 7. Final temperature of mixture Part 4 Calculations for Enthalpy Cheat) of Solution for the Dissolution of a Salt 1. Temperature change of solution, 2. Heat change of water Show calculation. 3. Heat change of salt sp. ht. of Part 5 KBr 0.439 J/g oC 4. Total enthalpy change, equation 25.11 Show calculation. 5. AH, (Imol salt Equation 25.12 Show calculation.

Explanation / Answer

Molar mass KBr = 119 g/mol (39.1+79.9)

Mol of salt = 5g/119 g/mol = 0.042 mol KBr
