Data:
[tex]M_{concentrated} = 10\:mol[/tex]
[tex]V_{concentrated} = ?[/tex]
[tex]M_{dilute} = 5\:mol[/tex]
[tex]V_{dilute} = 100\:mL[/tex]
Formula: Dilution Calculations
[tex]M_{concentrated} * V_{concentrated} = M_{dilute} * V_{dilute} [/tex]
Solving:
[tex]M_{concentrated} * V_{concentrated} = M_{dilute} * V_{dilute} [/tex]
[tex]10 * V_{concentrated} = 5 * 100 [/tex]
[tex]10V_{concentrated} = 500[/tex]
[tex]V_{concentrated} = \frac{500}{10} [/tex]
[tex]\boxed{\boxed{V_{concentrated} = 50\:mL}} \end{array}}\qquad\quad\checkmark[/tex]
Answer:
B. 50.0 mL
