$\text{Concentration}$ $=$ $\text{Moles of solute"/"Volume of solution}$
$\text{Concentration}$ $=$ $\text{Moles of solute"/"Volume of solution}$
$=$ $\frac{16.7 \cdot g}{142.04 \cdot g \cdot m o {l}^{-} 1} \times \frac{1}{0.125 \cdot L}$ $=$ $0.940 \cdot m o l \cdot {L}^{-} 1$ with respect to sodium sulfate.
