# A student measures 14.0 g of copper (II) nitrate and adds it to a 250 mL volumetric flask. What should be the recorded molarity?

$\text{Concentration "="Moles"/"Volume of solution}$ $= 0.3 \cdot m o l \cdot {L}^{-} 1$
$\text{Concentration } =$
$\frac{14.0 \cdot g}{187.56 \cdot g \cdot m o {l}^{-} 1} \times \frac{1}{0.250 \cdot L} \cong 0.30 \cdot m o l \cdot {L}^{-} 1$ with respect to copper nitrate.
