How do you make a 6 dilution?

To find the final Molarity:

First there is M₁V₁=M₂V₂.

switch it to equal M₂ so: M₁ x (^V1/_V2)^{#of times diluting} = M₂

Example: Dilute a 10 M H₂SO₄ six times by taking a 50mL aliquot and adding distilled water until 130mL each time.

M₁= 10M, V₁= 50mL, V₂= 130mL, M₂= ?, #of dilutions=6 (Make sure both V's are in the same unit!)

10 x (⁵⁰/₁₃₀)⁶ = M₂ M₂= 0.03237... sig.dig. and M₂= 0.03 M H₂SO₄!

To do this you have to take 50mL out of the first solution and add 80mL distilled water. Repeat with new solution. Again, 4 more times.
