Question

Compounds of boron with hydrogen are called boranes One of these
boranes has the emperical formula BH3 and a molecular weight of 28
am What is its atomicity

Geetha · Accepted Answer

BH3 molar mass = 10
81 + 3 × 1 008 = 13
87 amuAtomicity = Molecular massEmpirical formula mass of BH3      = 2813
87 =2So the molecular formula of the diborane = BH3 × 2 = B2H6

Compounds of boron with hydrogen are called boranes. One of these boranes has the emperical formula BH3 and a molecular weight of 28 am. What is its atomicity
