The mass of a sulfur atom is 32.0 u, and the mass of a fluorine atom is 19.0 u. What is the mass of a mole of sulfur hexafluoride (UF₆)? A) 41.0 g B) 20.5 g C) 106 g D) 146 g E) 211 g

Question

Quizplus · Accepted Answer

The mass of sulfur hexafluoride (SF6) can be calculated by adding the mass of one sulfur atom (32.0 u) to the mass of six fluorine atoms (6 x 19.0 u = 114.0 u), giving a total of 146.0 u. Since the molar mass is the mass of one mole of a substance in grams, the molar mass of SF6 is 146.0 g/mol.
