Stock solution: C₁ = 772 mM, V₁ = ? mL
Diluted solution: C₂ = 25 mM, V₂ = 100. mL
For dilution: C₁V₁ = C₂V₂
Then, V₁ = V₂ × (C₂/C₁)
Volume of stock solution, V₁ = (100 mL) × (25/772) = 3.24 mL
Diluted solution: C₂ = 25 mM, V₂ = 100. mL
For dilution: C₁V₁ = C₂V₂
Then, V₁ = V₂ × (C₂/C₁)

M1V1 = M2V2
(772)(x) = (100)(25)
solve for x
(772)(x) = (100)(25)
solve for x
