Final answer:
In 1.3 moles of C12H22O11, there are approximately 9.394 × 10^25 carbon atoms, as calculated using Avogadro's number and the carbon atom count per molecule of the compound.
Step-by-step explanation:
To determine how many atoms of carbon are in 1.3 moles of C12H22O11, we will use Avogadro's number which states that 1 mole of any substance contains 6.022 × 1023 representative particles (atoms, molecules, etc.).
Since we want to find the number of carbon atoms, and there are 12 carbon atoms in each molecule of C12H22O11, we multiply the number of moles by Avogadro's number and then by 12 (the number of carbon atoms per molecule).
The calculation will look like this:
1.3 moles × 6.022 × 1023 atoms/mole × 12 atoms of carbon/molecule of C12H22O11 = Number of carbon atoms.
Carrying out this calculation, we find that there are approximately 9.394 × 1025 carbon atoms in 1.3 moles of C12H22O11.
