Interpret the masses as 1.99×10^−23 g and 1.68×10^−24 g. The ratio is
(1.99×10^−23) / (1.68×10^−24) = (1.99/1.68) × 10^(−23 − (−24)) = (1.99/1.68) × 10 ≈ 1.18333 × 10 = 11.8333…
Rounded to the nearest tenth: 11.8
So a carbon-12 atom is about 11.8 times more massive than a neutron.
(1.99×10^−23) / (1.68×10^−24) = (1.99/1.68) × 10^(−23 − (−24)) = (1.99/1.68) × 10 ≈ 1.18333 × 10 = 11.8333…
Rounded to the nearest tenth: 11.8
So a carbon-12 atom is about 11.8 times more massive than a neutron.
