Question

Determine a massa de um átomo de carbono12 em gramas

Answer 1

The mass of an atom of carbon-12 is 1.993 × 10⁻²³ g.

1 C atom has a mass of 12 u.

1 mol of C atoms has a mass of 12 g.

∴ Mass of 1 C atom = 12 g/6.022 × 10²³ C atoms = 1.993 × 10⁻²³ g

Answer 2

I believe it would be 1.660539040 × 10−24 gram.
