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