Question

In Lab 8 you will be determining the enthalpy change accompanying various phase changes. In this pre-lab assignment you will go through some of the calculations required for Part 2 of this experiment, in which you determine Delta Hfusion of ice. To determine Delta Hfusion of ice you will essentially add ice to water, allow the ice to melt, and note the temperature change of the water. Let's first get an idea of the ratio of water to ice that you will need. The value for the Delta Hfusion of ice is 6.0 kJ/mol. Let's suppose you start with 39.9 g of ice. Determine AH for melting 39.9 g of ice. Tries 2/99 Previous Tries

Explanation / Answer

the mol weight of ice:18 so,mol of ice added:2.2166moles and Hfusion=13.3KJoule
