Answer : The molar heat of fusion for substance X is, 775.6 cal/mol
Explanation :
First we have to calculate the moles of substance X.
Given:
Molar mass of substance X = 58.45 g/mole
Mass of substance X = 326.0 g
Now put all the given values in the above expression, we get:
Now we have to calculate the molar heat of fusion for substance X.
where,
Q = heat releases = 4325.8 cal
= molar heat of fusion for substance X = ?
n = moles = 5.577 mol
Now put all the given values in the above expression, we get:
Thus, the molar heat of fusion for substance X is, 775.6 cal/mol
