NaCl has a Delta. Hfus = 30. 2 kJ/mol. What is the mass of a sample of NaCl that needs 732. 6 kJ of heat to melt completely? Use

tia_tia [17]

The mass of NaCl sample has been 24.3 g. Thus, option A is correct.

The heat of fusion has been the amount of heat required to convert 1 mole of substance into solid to liquid state.

The heat required has been given as:

$Q=m\Delta H$

<h3>Computation for the mass of NaCl</h3>

The given solution has heat of fusion, $\Delta H_{fus}=30.2\rm kJ/mol$

The heat required to melt the sample has been, $Q=732.6\;\rm kJ/mol$

Substituting the values for the mass of NaCl

$\rm 732.6\;kJ/mol=Mass\;\times\;30.2\;kJ/mol\\\\
Mass=\dfrac{732.6}{30.2}\;g\\\\
 Mass=24.3\;g\\$

The mass of NaCl sample has been 24.3 g. Thus, option A is correct.
