One mole (mol) of glucose (molecular mass = 180 daltons) is:

• A. 180 liters of glucose at STP
• B. 6.022 × 10^{23} molecules of glucose weighing 1 gram
• C. 180 grams of glucose
• D. 1 mole of glucose contains 180 molecules

Answer: (C)

Verified step by step guidance

1. Recall the definition of a mole: 1 mole of any substance contains Avogadro's number of particles, which is \$6.022 \times 10^{23}$ entities (atoms, molecules, etc.).
2. Understand that the molecular mass of glucose is given as 180 daltons (or grams per mole), meaning 1 mole of glucose weighs 180 grams.
3. Recognize that 1 mole of glucose contains \$6.022 \times 10^{23}$ molecules, not 180 molecules, so the statement about 180 molecules is incorrect.
4. Note that glucose is a solid or liquid under standard conditions, so it does not occupy 180 liters at STP; gases occupy volume at STP, not solids or liquids.
5. Conclude that the correct interpretation is: 1 mole of glucose corresponds to 180 grams of glucose and contains \$6.022 \times 10^{23}$ molecules.
