FAQ

What is the molar mass of Kr?

M(Kr) = 83.798 g/mol

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

Only in units: the relative atomic mass Ar(Kr) = 83.798 has no unit, and the molar mass M(Kr) = 83.798 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of Kr?

m = n × M = 2 mol × 83.798 g/mol = 167.596 g.
