1g = 6.022 x 1023 AMU

Explanation:

An atomic mass unit or AMU is a physical constant which is equal to one-twelfth of the mass of an unbound carbon-12 atom.

One unified atomic mass unit is equal to 1.66 yoctograms = 1.66053904020 x 10-24 g.

1 AMU is equivalent to 1.66 x 10-24 grams and 1 gram is equivalent to 6.022 x 1023 AMU.

Thus, 1g = 6.022 x 1023 AMU.
