Triton-100X is the same as 100%. Does it also mean that if a solution is 50X then it is 50%? How come?

THanks

It's Triton-X100... the number is not a reference to concentration... after all there is Triton-X114...
So the X and the 100 are only the name of the product.

If you want a 2% solution you take 2ml in 100ml final, like any other product.

50x does not mean 50%,
50 x means 50 times what is concidered normal for use.
In the case of Triton, it does not tell anything about the conc.

Consider the following (imaginary) recipe for a media

Per liter

KH2PO4 = 5g
K2HPO4 = 2g
MgSO4 = 3g

Now, if I want to prepare a 5X of the media, the formulation would have a 5-fold increase

KH2PO4 = 25g
K2HPO4 = 10g
MgSO4 = 15g

As for %, always remember

x% = (x grams/100mL)
