Which of the following has the greatest mass? 1 mole of uranium (u) 1 mole of oxygen (o) 1 mole of sodium (na) 1 mole of chlorine (cl)

To determine which has the greatest mass, we need to find out the molecular mass of each element:

Uranium (U) = 238 g/mol
Oxygen (O) = 16 g/mol
Sodium (Na) = 23 g/mol
Chlorine (Cl) = 35.45 g/mol

Therefore, if we have one mole of each element, the element with the greatest mass is 238 grams or Uranium.
