FAQ

What is the molar mass of W?

M(W) = 183.84 g/mol

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

Only in units: the relative atomic mass Ar(W) = 183.84 has no unit, and the molar mass M(W) = 183.84 g/mol is the mass of one mole of atoms (6.022 × 10²³ of them).

How many grams are in 2 moles of W?

m = n × M = 2 mol × 183.84 g/mol = 367.68 g.
