To calculate the molar mass of UF6 (uranium hexafluoride), you need to know the atomic masses of uranium (U) and fluorine (F). The atomic mass of uranium is approximately 238.03 g/mol, and the atomic mass of fluorine is approximately 18.998 g/mol.
UF6 consists of one uranium atom and six fluorine atoms. Therefore, the molar mass of UF6 can be calculated as follows:
Molar mass of UF6 = (1 × atomic mass of U) + (6 × atomic mass of F)
Molar mass of UF6 = (1 × 238.03 g/mol) + (6 × 18.998 g/mol)
Molar mass of UF6 = 238.03 g/mol + 113.988 g/mol
Molar mass of UF6 = 352.018 g/mol
So, the molar mass of UF6 is approximately 352.018 g/mol.
