Agas occupies a volume of 410 ml at 27°c and 740 mm hg pressure. calculate the volume the gas
would occupy at 250.°c and 680 mm hg pressure.

The volume of gas is 58.22 L which will occupy at 250.°C and 680 mm Hg pressure.

Explanation:

Given:

Temperature = 27°C

To make it into kelvin   = 27+273

 = 300K

Pressure  =740mm Hg

to make it in atm.  =

= 0.973atm

n   = 2.3 moles

Volume of gas =?

 As we know according to the formula

 PV   = nRT

On substituting the values

 =

= 58.22 L

Therefore, 58.22L volume of gas will occupy at 250.°C and 680 mm Hg pressure.

the electronic configuration of an atom with eight electrons is 1s²2s²2p⁴. the orbital diagrams are shown in the figure.

as per the hunds rule:

1. electrons tend to avoid being in the same orbital as per as practicable.

2. electrons in different orbitals of the same energy will have their spin parallel.

this can be illustrated from the multiplicity of the orbitals of the atom. as there are four electrons in the p orbital and p orbital has 3 sub-shells. the electrons can be fed in different ways as shown in the figure but the correct orbital diagram will be as per the hunds rule.
