FAQ

What is the molar mass of Xe?

M(Xe) = 131.29 g/mol

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

Only in units: the relative atomic mass Ar(Xe) = 131.29 has no unit, and the molar mass M(Xe) = 131.29 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Xe?

m = n × M = 2 mol × 131.29 g/mol = 262.58 g.
