• D. 98.08 g/mol

Answer: (B)

Verified step by step guidance

1. Identify the molecular formula of glucose, which is C6H12O6. This means glucose contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms.
2. Find the atomic masses of each element from the periodic table: Carbon (C) ≈ 12.01 g/mol, Hydrogen (H) ≈ 1.008 g/mol, Oxygen (O) ≈ 16.00 g/mol.
3. Calculate the total mass contributed by each element by multiplying the number of atoms by their atomic masses: For carbon, multiply 6 by 12.01; for hydrogen, multiply 12 by 1.008; for oxygen, multiply 6 by 16.00.
4. Add the masses of all the elements together to get the molar mass of glucose: Total molar mass = (6 × 12.01) + (12 × 1.008) + (6 × 16.00).
5. Sum these values to find the molar mass of glucose in grams per mole (g/mol). This final value represents the mass of one mole of glucose molecules.
