Boron exist in different allotropic forms. All allotropic form contains icosahedral units (icosahedral is regular shape with 12 corner & 20 faces) with boron atoms at all 12 corners and all bonds are equivalent. Calculate heat evolved at constant pressure (in KJ) per mole of boron atoms undergoing above change it `DeltaH_(BE)(B-B) =200 KJ//\"mol\"`. Report you answer after dividing by 100
