Molar and molecular weight of TlNO3

• Molecular formula: TlNO3 or NO3Tl
• Relative molecular weight of TlNO3: 266.3882
• Molar mass of TlNO3: 266.3882 g/mol (0.26639 kg/mol)

Calculation of the relative molecular and molar mass of TlNO3

• Mr[TlNO3] = Ar[N] + Ar[O] * 3 + Ar[Tl] = 14.0067 + 15.9994 * 3 + 204.3833 = 266.3882
• Molar mass (kg/mol) = Mr[TlNO3] : 1000 = 266.3882 : 1000 = 0.26639 kg/mol

TlNO3: percent composition by element

• Nitrogen (N) = 14.0067 : 266.3882 * 100 = 5.258 %
• Oxygen (O) = 47.9982 : 266.3882 * 100 = 18.018 %
• Thallium (Tl) = 204.3833 : 266.3882 * 100 = 76.724 %
