Final answer:
The total number of molecules in a 0.10-mole sample of SO2 is 6.0 × 10²², which is calculated by multiplying the number of moles by Avogadro's Number.
Step-by-step explanation:
The total number of molecules in a 0.10-mole sample of SO2 can be calculated using Avogadro's Number, which is 6.02 × 1023 molecules/mol.
To find the total number of molecules in the sample, you simply multiply the number of moles by Avogadro's Number:
(0.10 mol) × (6.02 × 1023 molecules/mol) = 6.02 × 1022 molecules of SO2.
The correct answer is 6.0 × 1022 molecules of SO2.
