(Polar molecules, Non-polar molecules, etc.)

When calculating the molar mass of 2 moles , I calculated the 14.0067 x 4 because I thought it was equivalent to 4 nitrogen atoms. Can someone explain why I'm wrong please? I know now that the molar mass should have been just 14.0067 x 2.
Unless they are the same element, all diatomic molecules are somewhat polar because every element has at least a slight difference in electronegativity that causes one atom to pull on the shared electrons more than the other.
