What is the mass of 0.240 mol of glucose (C6H12O6)?

• A. 72.0 g
• B. 43.2 g
• C. 24.0 g
• D. 38.7 g

Answer: (D)

Verified step by step guidance

1. Identify the molecular formula of glucose, which is C6H12O6.
2. Calculate the molar mass of glucose by summing the atomic masses of all atoms in the formula: multiply the atomic mass of carbon (C) by 6, hydrogen (H) by 12, and oxygen (O) by 6, then add these values together. Use the approximate atomic masses: C = 12.0 g/mol, H = 1.0 g/mol, O = 16.0 g/mol.
3. Write the formula for mass from moles: \(\text{mass} = \text{moles} \times \text{molar mass}\).
4. Substitute the given number of moles (0.240 mol) and the calculated molar mass of glucose into the formula.
5. Multiply the moles by the molar mass to find the mass of glucose in grams.
