Answer: The mass of the sample will be 1417.7 grams.
Explanation:
We are given:
[tex]\Delta H_{fusion}=30.2kJ/mol[/tex]
This means that 1 mole of NaCl has an enthalpy of fusion of 30.2 kJ
1 mole of NaCl has a mass of 58.44 grams.
So, 30.2 kJ of heat is require for a mass 58.44 grams of NaCl
So, 732.6 kJ of heat will be required for = [tex]\frac{58.44g}{30.2kJ}\times 732.6 kJ[/tex] = 1417.65 grams of NaCl.
Hence, the mass of NaCl sample will be 1417.7 grams.
