The molar heat of fusion for substance X , given the data is 775.6 cal/mol
<h3>How to determine the mole of the substance X</h3>
- Mass = 326 g
- Molar mass = 58.45 g/mol
- Mole = ?
Mole = mass / molar mass
Mole = (326 / 58.45) moles
<h3>How to determine the heat of fussion</h3>
- Mole (n) = (326 / 58.45) moles
- Heat (Q) = 4325.8 cal
- Heat of fusion (ΔHf) = ?
Q = n × ΔHf
4325.8 = (326 / 58.45) × ΔHf
4325.8 = (326 × ΔHf ) / 58.45
Cross multiply
326 × ΔHf = 4325.8 × 58.45
Divide both sides by 326
ΔHf = (4325.8 × 58.45) / 326
ΔHf = 775.6 cal/mol
