Question

How much energy does it take to melt a 16.87 g ice cube? 
= 6.02 kJ/mol

Quizplus · Accepted Answer

To calculate the energy needed to melt the ice cube, we need to use the heat of fusion of water, which is given as 6.02 kJ/mol.

First, we need to find the number of moles of water in the ice cube:

16.87 g x (1 mol/18.02 g) = 0.936 mol

Then, we can calculate the energy needed to melt the ice cube:

0.936 mol x 6.02 kJ/mol = 5.64 kJ

Therefore, the answer is D) 5.64 kJ.
