A diagram of the composition of air would be the air's chemical formula and it's structure.
Osmium is the densest<span> element on earth. It is a hard, weak, pale blue white move metal in the platinum aggregate that is found as a follow component in amalgams, generally in platinum minerals. Osmium is the densest normally happening component, with a thickness of22.59 g/cm3. There is still some open deliberation that Iridium is the denser component as per hypothetical figurings yet starting at now, Osmium has the most noteworthy measured thickness. </span>
Answer: The new volume of gas is 28.5 L
Explanation:
The combined gas equation is,
where,
= initial pressure of gas = 1.00 atm (at STP)
= final pressure of gas = 102.6 kPa = 1.01 atm (1 kPa= 0.0098 atm)
= initial volume of gas = 10.0 L
= final volume of gas = ?
= initial temperature of gas = 
(STP)
= final temperature of gas = 
Now put all the given values in the above equation, we get:
The new volume of gas is 28.5 L
Try to understand all the rules and laws like:
Aufbau Principle
Hund's rule
Pauli exclusion principle...
Then, you should understand the way in which you can fill the electrons in the orbitals!!
