Answer
66.30 mL
Explanation
Given parameters:
Initial concentration, C₁ = 5.724 M
Final volume, V₂ = 183.95 mL
Final volume, V₂ = 183.95 mLFinal concentration, C₂ = 2.063 M
What to find:
The initial volume, V₁
Step-by-step solution:
Using the dilution law:
[tex]C_1V_1=C_2V_2[/tex]Substitute the given parameters into the formula to get V₁
[tex]\begin{gathered} 5.724M\times V_1=2.063M\times183.95mL \\ \text{Divide both sides by 5.724M} \\ \frac{5.724M\times V_1}{5.724M}=\frac{2.063M\times183.95mL}{5.724M} \\ V_1=66.30\text{ mL} \end{gathered}[/tex]Hence, 66.30 mL of 5.724 M HNO3 are needed to prepare a 183.95 mL of 2.063 M HNO3?
