Cobalt has the greatest mass while iron has the least mass.

Explanation:

Atomic masses are numerically equal to molar masses (mass in 1 mole of an element or molecule).

So, based on the values given, cobalt has the greatest mass since 1 mole of cobalt has 58.9332 grams. On the other hand, iron has the least mass since 1 mole of iron only has 55.847 grams.
