The atomic mass of the element niobium (Nb) is 92.906 amu. Which measurement is correct?(1 point)

Question

Responses

1 mole of Nb = 92.906 grams
1 mole of Nb = 92.906 grams

1 gram of Nb = 92.906 moles
1 gram of Nb = 92.906 moles

1 mole of Nb = 92.906 atoms
1 mole of Nb = 92.906 atoms

1 gram of Nb = 92.906 atoms

Answer 1

The correct measurement is:

1 mole of Nb = 92.906 grams.

This is based on the definition of atomic mass: the atomic mass of an element in atomic mass units (amu) is numerically equivalent to the mass of one mole of that element in grams.
