Answer:

[tex]\Delta S=51.1\frac{J}{K}[/tex]

Explanation:

Hello!

In this case, since the entropy and enthalpy are related via the following equation for any process:

[tex]\Delta S=\frac{m\Delta H}{T}[/tex]

As this problem relates the enthalpy and entropy of fusion, given the mass, melting temperature and heat of fusion, we compute the change in entropy of fusion as shown below:

[tex]\Delta S=\frac{0.0419kg*333,000\frac{J}{kg} }{273.15K}\\\\\Delta S=51.1\frac{J}{K}[/tex]

Best regards!
