Molar and molecular weight of BeI2

• Relative molecular weight of BeI2: 262.821122
• Molar mass of BeI2: 262.821122 g/mol (0.26282 kg/mol)

Calculation of the relative molecular and molar mass of BeI2

• Mr[BeI2] = Ar[Be] + Ar[I] * 2 = 9.012182 + 126.90447 * 2 = 262.821122
• Molar mass (kg/mol) = Mr[BeI2] : 1000 = 262.821122 : 1000 = 0.26282 kg/mol

BeI2: percent composition by element

• Beryllium (Be) = 9.012182 : 262.821122 * 100 = 3.429 %
• Iodine (I) = 253.80894 : 262.821122 * 100 = 96.571 %
