**Question: Which sample represents the greatest number of moles?**Options:a) 44.01 g CO₂ b) 1.0 moles C₃H₈ c) 6.022 x 10²³ molecules C₄H₁₀ d) 18.02 g H₂O e) All of the sample have the same number of moles. **Diagram Explanation:**The image includes a glass of water. Zoomed in, there's a molecular diagram showing that water molecules have a fixed ratio of hydrogen (two atoms) to oxygen (one atom).**Text Box in Diagram:**Water (A Compound): Water molecules have a fixed ratio of hydrogen (two atoms) to oxygen (one atom).

The moles of a substance can be calculated as follows: Moles of substance=Mass of substanceMolar mass of substance (a) 44.01 g of CO2 Moles of CO2=Mass of CO2Molar mass of CO2=44.01 g44.01 g/mol=1.0 mol (b) 1.0 moles of C3H8 (c) 6.022×1023 molecules of C4H10 As we know, 6.022×1023 molecules = 1 molSo, 6.022×1023 molecules of C4H10=1 mol of C4H10 (d) 18.02 g of H2O Moles of H2O=Mass of H2OMolar mass of H2O=18.02 g18.02 g/mol=1.0 mol As we can see that all the samples have the same number of moles. Hence, the correct option is (e).
