The molar heat of fusion of gold is 12.550 kJ mol–1. At its melting point, how much mass of melted gold must solidify to release
1 answer:
The mass of melted gold to release the energy would be 3, 688. 8 Kg
<h3>How to determine the mass</h3>It is important to note that the formula for energy is
Q = n × HF
Where
n = number of moles
HF = heat of fusion
Let's find number of moles
235.0 = n × 12.550
number of moles = = 18. 725 moles
The molar mass of Gold is 197g/ mol
We have that;
Number of moles = mass/ molar mass
Mass = number of moles × molar mass
Substitute the values
Mass = 18. 725 × 197
Mass = 3, 688. 8 Kg
Thus, the mass of melted gold to release the energy would be 3, 688. 8 Kg
