Final answer:
The atomic mass of hydrogen in u is approximately 1.00784.
Step-by-step explanation:
The atomic mass of hydrogen is calculated by converting the mass of an atom from grams to unified atomic mass units (u). One atomic mass unit is defined as one-twelfth the mass of a carbon-12 atom. To convert grams to u, divide the mass in grams by the Avogadro's number and multiply by the ratio of u to grams, which is approximately 6.022 x 10^23 u/g.
For example, to find the atomic mass of hydrogen in u:
- Mass of hydrogen atom in grams = 1.6736 x 10^-24 g
- Divide this value by Avogadro's number (6.022 x 10^23 atoms/mol).
- Multiply this value by the ratio of u to grams (approximately 6.022 x 10^23 u/g).
- The result is approximately 1.00784 u.
