It requires 113 J to melt 1 .00  g of sodium metal at its normal melting point of 98  ° C . Calculate the molar hear of fusion of sodium

Interpretation Introduction

Interpretation:

Molar heat of fusion of sodium must be calculated.

Concept Introduction:

Molar heat of fusion is the heat energy required to convert 1 mole solid to 1 mole liquid at the melting point of the solid.

Explanation

Given information:

Melting point of sodium as 980C. Heat energy required to melt 1g sodium is 113J.

As per the definition of molar heat of fusion we have to find out the heat energy required to melt one mole sodium. The heat energy for 1g sodium is given which we can use for finding the heat energy for one mole
