the answer would be equal to 0.253 mol
Answer:
1. The oxidation number of a free element is always 0.
2. The oxidation number of a monatomic ion equals the charge of the ion.
3. The oxidation number of H is +1, but it is -1 in when combined with less electronegative elements.
4. The oxidation number of O in compounds is usually -2, but it is -1 in peroxides.
Explanation:
The average kinetic energy and rms speed of N₂ molecules at STP is
and 
Given,

The average kinetic energy of a molecule is given by,
where k is the Boltzmann constant and Tis the absolute temperature of the gas.


The rms speed of
molecules is given by

The average kinetic energy of a gas's particles is inversely related to its temperature. As the gas warms, the particles must travel more quickly since their mass is constant.
The average kinetic energy (K) is equal to one half of the mass (m) of each gas molecule times the RMS speed (vrms) squared.

Science doesn't make moral judgments, doesn't make aesthetic judgments, doesn't tell you how to use scientific knowledge, doesn't draw conclusions about supernatural explanations. So that's why I think it has limitations.
Moles of solute does not change.
