Answer
0.750 M
Explanation
Given:
Initial volume, V₁ = 15.0 mL
Initial molarity, M₁ = 2.00 M
Final volume, V₂ = 40.0 mL
What to find:
The molarity (M₂) of the dilute solution.
Step-by-step solution:
The molarity (M₂) of the dilute solution can be determined using the dilution formula.
[tex]M_1V_1=M_2V_2[/tex]
Substitute the values of the given parameters into the formula, we have
[tex]\begin{gathered} 2.00M\times15.0mL=M_2\times40.0mL \\ \\ M_2=\frac{2.00M\times15.0mL}{40.0mL} \\ \\ M_2=0.750\text{ }M \end{gathered}[/tex]
Thus, the molarity (M₂) of the dilute solution is 0.750 M
