Chemistry · Some Basic Concepts of Chemistry

Given that the mass of a single \( ^{12}\text{C} \) atom is \( 1.992648 \times 10^{-23}\text{ g} \), the absolute mass in grams corresponding to \( 1\text{ amu} \) (unified atomic mass unit) is equal to:

1. A
   \( 1.66056 \times 10^{-24}\text{ g} \)
2. B
   \( 1.992648 \times 10^{-24}\text{ g} \)
3. C
   \( 1.66056 \times 10^{-27}\text{ g} \)
4. D
   \( 6.02214 \times 10^{-24}\text{ g} \)
