FAQ

What is the molar mass of Tb?

M(Tb) = 158.93 g/mol

How is the molar mass of terbium different from its atomic weight?

Only in units: the relative atomic mass Ar(Tb) = 158.93 has no unit, and the molar mass M(Tb) = 158.93 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Tb?

m = n × M = 2 mol × 158.93 g/mol = 317.86 g.
