You have 500ml of a 10x buffer stock. You need to make 500ml of 1x buffer to use for an experiment. How much concentrated buffer and water would you need to use?

Ahh, I keep getting like two different answers for this one.

Imagine that you needed a litre 1x from 10x.  100 mls 10x + 900 mls water would give you the required dilution but this would be twice as much as you need so half the amounts: 50 mls 10x + 450 mls water gives you what you need.
