If the mass of a phosphorus atom is 30.97 amu, what is the atom's molar mass?

Answer 1

It is 30.97 grams. Molar mass is simply the amu's expressed in grams

Answer 2

a million amu = a million.6605 × 10^-24 g; Avogadro's form = 6.0221 × 10^23 atoms/mole mass a million mole Au = 196.97 amu/atom(a million.6605×10^-24 g/a million amu)(6.0221 × 10^23 atoms/a million mole Au) = 196.ninety six g/mole of Au atoms
