Final answer:
To find the number of carbon atoms in 2 molecules of glucose (C6H12O6), multiply the number of carbon atoms in one molecule (6) by the number of molecules (2), resulting in 12 carbon atoms.
Step-by-step explanation:
The question is asking how many atoms of carbon are present in 2 molecules of sugar, which has the chemical formula C6H12O6. This compound is commonly known as glucose. One molecule of glucose contains 6 carbon atoms. Therefore, if we have 2 molecules of glucose, we simply multiply the number of carbon atoms in one molecule by 2:
6 carbon atoms/molecule × 2 molecules = 12 carbon atoms
Hence, the correct answer is B) 12 atoms.
