Use the following schematic "lattice" and →    the definitions to resolve the following exercise:

Exercise Calculate the volume of a $12.6\frac{g}{L}$ solution of nitric acid containing $30.1$ moles of pure acid. Solution (Click): Scheme and Formulas: .......... Calculation: ..........$m_{so}=n{so}\cdot M_{so}$ $=$ $30.1\cdot 63.0=1896.3\;g$
because $M_{so}=M_{HNO_3}=63.0\frac{g}{mol}$
$V_{S}$ $=$ $\frac{m_{so}}{c_{so}}$ = $\frac{1896.3}{12.6}$ = $150.5 \; L$
