• Lidocaine is available as a 2.0% (w/v) solution.
,
• The mass of solute is 60. mg of lidocaine.
To find the volume of this solution, we use the following equation.
[tex](\frac{w}{v})=\frac{Mass\text{ of solute}}{Volume\text{ of solution}}[/tex]
Use the given magnitudes and solve for volume.
[tex]\begin{gathered} 0.02=\frac{60mg}{V} \\ V=\frac{60mg}{0.02} \end{gathered}[/tex]
But, we need to use grams.
[tex]V=\frac{0.060g}{0.02}=3[/tex]
Therefore, the volume of this solution is 3.0 mL.
