Calculate the atomic mass of lead, if the mass of 0.2 mol of it equals 41.4 grams

The atomic mass of lead : 207 g/mol

The mass of this basic particle is expressed in atomic mass units  

This atomic unit uses the standard atomic mass, that is, the C-12 isotope

1 atom C-12 = 12 atomic mass units

The atomic mass of an element (amu = u = g/mol) = the mass in grams of one mole of an element.

The mass of 0.2 mol of Lead equals 41.4 grams, so the atomic mass :
