a mixture of ideal gases having a total mass of 28.3 g is placed in a 8 l vessel at 275.0 k. the equilibrium pressure is measured to be 1.8 bar. calculate the average molar mass of the gas mixture.
average molar mass of the gas mixture is 45.09 g/mol
Calculation :
We have ,
Total mass = 28.3 g , volume = 8L
Temperature = 275 k , pressure = 1.8 bar
first we have to find mole (Total) of gases .
PV =NRT
(1.77)*(8) = N(total)*(0.082057)*(275K)
N(total) = 0.6276 mole
Now, we know,
(mole) n = mass/molar mass
n (total)= Total mass/average molar mass
Average molar mass = Total mass/n total
= 28.3 g/0.6276 mole
Average molar mass = 45.09 g/mol
In chemistry, the molar mass of a chemical compound is defined as the mass of a sample of that compound divided by the amount of substance. The amount of a substance is the number of moles of that sample measured in moles. Molar mass is mass, not a molecular property of a substance. Molar mass is the average of many instances of a compound, which often differ in mass due to the presence of isotopes. Most commonly, molar mass is calculated from standard atomic masses, so it is a global average and a function of the relative isotopic abundances of constituent atoms on Earth.

Exothermic reaction that has an overall increase in entropy is always spontaneous.
Exothermic reactions are defined as "reactions with a negative total standard enthalpy change ΔH⚬." Exothermic reactions typically produce heat.An exothermic reaction is one that releases energy in the form of light or heat. Thus, in an exothermic process, energy is transferred into the environment rather than taken from it, as in an endothermic reaction. The change in enthalpy ( ΔH) in an exothermic reaction is negative.
As a result, the net amount of energy required to start an exothermic reaction is less than the net amount of energy produced by the process. The net quantity of heat energy that passes through a calorimeter, an instrument used to quantify the heat emitted by a chemical reaction, is equal to the negative of the total energy change of the system.

For each atom in a Lewis structure, you should count how many electrons it "owns" in order to get the formal charges. All of its lone pair electrons as well as 50% of its bonding electrons should be counted. The formal charge is the discrepancy between the atom's number of valence electrons and the number it possesses.
How do you determine a double bond's formal charge?
Formal Charge is calculated as follows: [# of valence electrons on a neutral atom] - [(# of lone electron pairs) + (12 # bonding electrons)] Valence electrons = match the periodic table's group number (for representative elements). Lone Pairs are atoms with only one electron present. An electron pair counts as two since each electron counts as one.
What does a formal charge of +1 indicate?
The Formal Charge is the difference between the Group Number and the number of assigned electrons if the number of assigned electrons is less than the Group Number (for example, if the assigned number of electrons is 4 and the atom is nitrogen with a Group Number of 5 (Group V), the Formal Charge would be +1, meaning it is positive).
