Data:

M_(concentrated) = 2.5\:mol

V_(concentrated) = ?

M_(dilute) = 0.50\:mol

V_(dilute) = 100\:mL\to0.100\:L

Formula: Dilution Calculations


M_(concentrated) * V_(concentrated) = M_(dilute) * V_(dilute)

Solving:



M_(concentrated) * V_(concentrated) = M_(dilute) * V_(dilute)

2.5 * V_(concentrated) = 0.50 * 0.100

2.5V_(concentrated) = 0.05

V_(concentrated) = (0.05)/(2.5)

\boxed{\boxed{V_(concentrated) = 0.02\:L\:or\:20\:mL}} \end{array}}\qquad\quad\checkmark
