The maximum amount of XeF4 that could be produced is 0.5 moles.
XeF4 = Xe (g) 2 F2 (g) (g)
Xe and F2 have a mole ratio of 1:2. Because of this, the reaction would be limited by F2 when there is 1 mole of Xe and 1 mole of F2.
<h3>What is mole ratio?</h3>
The mole ratio is the ratio of any two compounds' mole amounts that are present in a balanced chemical reaction.
A comparison of the ratios of the molecules required to accomplish the reaction is given by the balancing chemical equation.
A mole ratio is a conversion factor used in chemical reactions to link the mole quantities of any two compounds. A conversion factor's numbers are derived from the balanced chemical equation's coefficients.

Neutrons = 118
<h3>Further explanation </h3>
The elements in nature have several types of isotopes
Isotopes are elements that have the same Atomic Number (Proton)
Atomic mass is <em>the average atomic mass of all its isotopes </em>
The most abundant isotope of gold (Au) is isotope Au-197
So the atomic mass of Au = 197
and the atomic number of Au = 79
Atomic mass is the sum of protons and neutrons
Atomic Number (Z) = Atomic mass (A) - Neutrons
Neutrons = A - Z
So neutrons for Au-197 :
