Molar and molecular weight of TeH2

• Molecular formula: TeH2 or H2Te
• Relative molecular weight of TeH2: 129.61588
• Molar mass of TeH2: 129.61588 g/mol (0.12962 kg/mol)

Calculation of the relative molecular and molar mass of TeH2

• Mr[TeH2] = Ar[H] * 2 + Ar[Te] = 1.00794 * 2 + 127.6 = 129.61588
• Molar mass (kg/mol) = Mr[TeH2] : 1000 = 129.61588 : 1000 = 0.12962 kg/mol

TeH2: percent composition by element

• Hydrogen (H) = 2.01588 : 129.61588 * 100 = 1.555 %
• Tellurium (Te) = 127.6 : 129.61588 * 100 = 98.445 %
