# What is "osmolarity" of a 171*g mass of sucrose in a 1*L volume of aqueous solution?

...but in the context is not the $\text{osmolarity}$ of sucrose equivalent to its $\text{molarity}$...?
$\text{Osmolarity"="Moles of solute"/"Volume of solution} = \frac{\frac{171 \cdot g}{342.30 \cdot g \cdot m o {l}^{-} 1}}{1.0 \cdot L} = \frac{1}{2} \cdot m o l \cdot {L}^{-} 1$
