Which relation for millimoles is correct?
ANumber of millimoles $= \text{Molarity} \times \text{Volume in mL}$
BNumber of millimoles $= \text{Normality} \times \text{Volume in mL}$
CNumber of millimoles $= \dfrac{\text{molar mass}}{\text{mass}} \times 1000$
DNumber of millimoles $= \dfrac{\text{mass}}{\text{equivalent weight}}$
Answer & Solution
Correct answer: A. Number of millimoles $= \text{Molarity} \times \text{Volume in mL}$
The chapter gives number of millimoles $= \dfrac{\text{wt. in g} \times 1000}{\text{mol. wt.}} = \text{Molarity} \times \text{Volume in mL}$. Option B corresponds to milliequivalents, not millimoles.
