FAQ

What is the molar mass of Sm?

M(Sm) = 150.36 g/mol

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

Only in units: the relative atomic mass Ar(Sm) = 150.36 has no unit, and the molar mass M(Sm) = 150.36 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Sm?

m = n × M = 2 mol × 150.36 g/mol = 300.72 g.
