What Is The Molar Mass Of Niobium Iodide?

The molar mass of niobium iodide can be calculated using the atomic masses of niobium and iodine and their respective stoichiometric coefficients in the compound. The atomic mass of niobium is 92.91 g/mol, and the atomic mass of iodine is 126.90 g/mol. The chemical formula for niobium iodide is NbI5, indicating that there are five moles of iodine for every mole of niobium.

To calculate the molar mass of niobium iodide, we first multiply the atomic mass of niobium by 1 (since there is only one mole of niobium in the compound) and add it to the product of the atomic mass of iodine and 5 (since there are five moles of iodine in the compound):

Molar mass of NbI5 = (1 x 92.91 g/mol) + (5 x 126.90 g/mol)

= 92.91 g/mol + 634.50 g/mol

= 727.41 g/mol.

Therefore, the molar mass of niobium iodide is 727.41 g/mol.
