Answer

Explanation:

Step1: Recall carbon - 12 mass in amu

By definition, the mass of a single carbon - 12 atom is 12.0000 amu.

Step2: Convert amu to grams

We know 1 amu = 1.6606×10⁻²⁴ g. So for a 12 - amu carbon - 12 atom, the mass in grams is $m = 12\times1.6606\times10^{-24}\text{ g}=1.99272\times 10^{-23}\text{ g}\approx1.9927\times 10^{-23}\text{ g}$.

Answer:

  1. B. 12.0000
  2. C. 1.9927×10⁻²³
