Question

calculate the mass of 1u an grams

Answer 1

1 u is the mass of 1/12th the mass of Carbon - 12 atom.

Now, let us first calculate the mass of one atom of C-12.

∵ No. of atom = Mass/At.mass × 6.022 × 10²³

⇒ 1 = Mass/12 × 6.022 × 10²³

∴ Mass = 12/6.022 × 10²³ g.

Now,. 1 u = 1/12 × Mass of One atom of C-12

∴ 1 u = 1/12 × 12/6.022 × 10²³

⇒ 1 u = 1/6.022 × 10²³

$\boxed{1.6 * 10^-^1^9}$
