How many moles of glucose (C6H12O6) are contained in 250.0 mL of a 0.400 M glucose solution?
A.1.60 mol
B.0.100 mol
C.0.00160 mol
D.0.625 mol
Explanation
Core Concept
Molarity relates moles of solute directly to liters of solution: moles = M multiplied by V. Converting first, 250.0 mL becomes 0.2500 L, then multiplying by 0.400 mol/L yields 0.100 mol. Glucose is a nonelectrolyte, so the dissolved particle count matches the formula-unit count and no dissociation factor enters. Reporting three significant figures honors the given data.
Correct Answer
B0.100 mol
