Answer:
0.9 moles of Hg contain 5.418×10²³ atoms
Explanation:
As we know, Avogadro's number (NA) is the amount of particles that are contained in 1 mol → 6.02×10²³
Let's make a rule of three for this:
6.02×10²³ atoms are contained in 1 mol of Hg
5.418×10²³ atoms would be contained in (5.418×10²³ . 1) / NA = 0.9 moles

Equation: (delta)G = (delta)H - T (delta)S
(delta)G stand for change in free energy. When it is positive, it is endergonic. When it is negative, it is exergonic.
H stands for bond energy and is enthalpy
T is the absolute temperature expressed in the Kelvin scale
S is entropy or disorder in the system
