Iron having Z=26 with electronic configuration as has 6 electrons in the 3d shell wherein 5 electrons are aligned parallely and 1 electron as antiparallel.
having electronic configuration as
has 5 electrons, all aligned in the same direction.
Iron, when kept in external magnetic field, the magnetic domains of the atom get aligned in one direction that means it becomes parallel and they remain parallel even after removing the magnetic field therefore, it is considered as ferromagnetic.
Volume of Oxygen O2 would be 33 L.
Solution : Given information - Mole (n) = 6.9 mol
Pressure (P) = 4.0 atm
Temperature (T) = 233 K
Universal gas constant (R) = 0.0821 L.atm/mol.K
Volume(V) is unknown , which we need to find.
Volume can be calculated by using the Ideal gas equation which is :
PV = nRT (Ideal gas equation)
On rearranging the above formula we will get :
Where , P = pressure , V = volume , n = mole , R = universal gas constant , T = temperature.
We will plugin the values of P , n , R and T in the ideal gas equation and then calculate Volume (V)
V = 32.998 L or 33 L
